关于c#:

I hate that there is no keyword to specify which exceptions are thrown from a method like in java. Its a much better way to document exceptions than using an XML comment. I would also want a much better syntax for generic constraints like oring and anding of constraints. Why a method can't return more than one value? Lack of support for aspect oriented programming in the language. Why can't you annotate each one of the property accessors with an attribute? Lack of builtin regexp support like in perl.

我是在冒险，因为我不能全职使用它，但无论如何我会尝试一下!

Perl 6

func("frew") != func ("frew") It annoys me, but there is good reason for it. In Perl 5 print (5 + 6) * 10 still gets me every now and then It may be easier to parse than Perl 5 in a lot of places, but it still kills my editor sometimes It still has a lot of the line noise Perl 5 which scares a lot of people. That means it's harder to get them excited etc. There are no libraries yet. This will be a non issue if Perl 6 does indeed end up supporting Perl 5, but that may be a burden not worth bearing. There's no REPL, or what rubyists would call irb. A solid interactive Perl 6 with tab completion, color coding, etc, would make using and learning it so much nicer. Currently the documentation is basically the English spec. Not exactly an easy read. I know it's a stupid cliche, but it's not out yet! (I am allowed to complain because I am helping :-P)

前三点是语言;剩下的并不是语言本身，而是它还没有问世的事实。

Delphi(又名Object Pascal)，我将讨论本机版本，而不是。net。

Var块! 语言中的接口在设计时就考虑到了COM的使用——因此比c#或Java要复杂得多。ie。涉及引用计数，除非显式禁用它。 没有尝试，只有最终结束; 对象创建过于显式: var obj: TMyObject; .．. obj:= TMyObject.Create; 试一试 .．. 最后 obj.Free; 结束;

而是像这样

auto obj: TMyObject; // compiler adds the default constructor call and the destructor call in a try/finally block. 

好吧，语言太好了，我真的想不出更多，所以我在这里强迫自己:内置类型，如字符串，整数..或者枚举最好有方法。ie。i. tostring代替IntToStr(i)。

VB6

仅Windows。 不再支持。 数组可以从任何数字开始，而不是全部归一化为0。 已编译的应用程序依赖于许多dll才能正常运行。 许多复杂的控件(如浏览器控件或复杂的代码段)在运行未编译的代码时往往会破坏IDE，但在编译后却可以正常工作。

我偶尔会用我喜欢的PHP，而Python会用得太多。

No namespace; everything is in a kind of very big namespace which is hell in bigger environments Lack of standards when it comes to functions: array functions take a needle as a first argument, haystack as second (see array_search). String functions often take the haystack first, needle second (see strpos). Other functions just use different naming schemes: bin2hex, strtolower, cal_to_jd Some functions have weird return values, out of what is normal: This forces you to have a third variable declared out of nowhere while PHP could efficiently interpret an empty array as false with its type juggling. There are near no other functions doing the same. $var = preg_match_all('/regexp/', $str, $ret); echo $var; //outputs the number of matches print_r($ret); //outputs the matches as an array The language (until PHP6) does its best to respect a near-retarded backward compatibility, making it carry bad practices and functions around when not needed (see mysql_escape_string vs. mysql_real_escape_string). The language evolved from a templating language to a full-backend one. This means anybody can output anything when they want, and it gets abused. You end up with template engines for a templating language... It sucks at importing files. You have 4 different ways to do it (include, include_once, require, require_once), they are all slow, very slow. In fact the whole language is slow. At least, pretty slower than python (even with a framework) and RoR from what I gather.

不过，我仍然喜欢PHP。这是网页开发的电锯:你想要一个小型到中型网站的速度非常快，并确保任何人都可以托管它(尽管配置可能不同)?PHP就在那里，它无处不在，只需要5分钟就可以安装一个完整的LAMP或WAMP堆栈。好吧，我现在要回去用Python工作了……

我讨厌Java(目前它是我最喜欢的语言)的五个方面，排名不分先后。

As much as I am a fan of Java Generics, there are a lot of oddities that arise from the way it was designed. As such there a myriad of annoying limitations with generics (some of which are the result of type-erasure). The way Object.clone() and the Cloneable interfaces work is totally broken. Instead of taking the high-road and making everything an object (a.la. SmallTalk), Sun wimped out created two distinct categories of data-types: Objects and primitives. As a result there are now two representations for fundamental data types and wierd curiosities such as boxing/unboxing and not being able to put primitives in a Collection. Swing is too complex. Don't get me wrong: there's a lot of cool stuff one can do with Swing but it is a great example of over-engineering. This final complaint is equally the fault of Sun and those whom have written XML libraries for Java. Java XML libraries are way too complicated. In order to simply read in an XML file, I often have to worry about what parser I am using: DOM or SAX? The APIs for each is equally confusing. Native support in the language for easily parsing/writing XML would be very nice. java.util.Date sucks. Not only is it unnecessarily complicated but all the useful methods have been deprecated (and replaced with others that increase complexity).
