我有一本书探讨了SNOBOL中的各种项目。第一章探讨了SNOBOL编程和语言的历史和文化，并花了一些时间论证一个优秀的程序员喜欢一种语言不是因为它的缺陷，而是尽管有缺陷。

我最喜欢的语言是Icon/Unicon。但还是有一些事情让我很恼火:

它不是很出名，也不是很受欢迎。 与PHP、Perl、Java等相比，它的库要小得多。数据库访问是通过ODBC完成的，这实际上非常烦人。 对于所有其他出色的列表处理，我想念PHP内置的explosion()和implode()。 它没有表常数。列表，是的，表格，不是。 它是一种编译(实际翻译)语言。

we have in operator, but no !in operator? dynamic array 'length' property - ya canna do array.length += 512; no exit statement - as in python's sys.exit(), etc. Sure, you can call C's exit, but unflushed output don't get flushed associative array literals + string literals suck string literals found as is inside an associative array literal are interpreted as static, thus this char[][char[]] hash = ["hello":"world","goodbye":"angels"]; doesn't work without some extra casting due to different length string literals despite a. I didn't ask it to be interpreted as static arrays b. static arrays aren't allowed in associative arrays anyways cyclic dependencies disallowed (want to port that java lib? Have fun redesigning the class hierarchy)

谁帮我检查一下;不确定它们是否都有意义。

Lua:

The built-in error system is absolutely horrendous You can implement a try-catch system by modifying the Lua interpreter; but it has no compatibility with the errors that are thrown by the built in functions. The fact they have __newindex instead of __setindex as the setter ... and __newindex is only fired when the key doesn't already exist. If it does, no metamethod is called at all. No good type comparison system. There's the type() function but it only handles the basic types (all tables are tables). It really needs to have a metamethod for type comparisons. I've implemented this before with an 'is' operator and a __type metamethod and it works really nicely. It's a bitch to define new keywords. You can do it, but the code inside Lua isn't well documented so it's kind of trial and error to find out how to get the result you want. This is a major issue when you want to implement the things I mentioned above yourself (not so much __setindex though, that's an easy modification). I can't use it in a web browser. Yeah not really a problem with the language itself, but damn, would I love to be able to use Lua instead of Javascript... :)

Common Lisp

缺少提供更现代功能的标准库(套接字，线程，…) 是否可以使用映射到本机窗口系统的标准化UI Scheme将lambda表达式赋值给变量并将变量直接作为函数调用使用的能力看起来比APPLY for FUNCALL更整洁。我猜这是使用多个名称空间的副作用 标准化的库源代码级打包系统，以便可以从多个实现中轻松使用它们

我想知道强类型的口齿不清会是什么样子

REBOL

REBOL是我最喜欢的语言之一。我不能说我有一个最喜欢的，尽管Haskell排名也很高。

Its odd syntax scares off many developers before they even give it a try. use [email rules url] [ ; A small DSL that sends email to people about URLs. rules: [ some [ into [ set email email! set url url! (send/subject email url reform [ "Check Out" url ]) ] ] ] ; Global context notify: func [ [catch] dsl [block!] ] [ unless parse dsl rules [ throw make error! "You screwed up somehow." ] ] ] notify [ [ a@b.com http://www.google.com ] [ b@c.com http://www.yahoo.com ] ] Recursive dialects are very easy to validate with PARSE but very difficult to evaluate. (Stacks can be helpful here.) REBOL has very poor integration with many popular technologies, particularly XML. I suspect this is partly arrogance, because the REBOL BLOCK! datatype can do almost everything XML can do. However, the real world has XML in it. No Unicode. Thanks to AltMe, REBOL's user community is very insular. I can understand why they want to use AltMe. It's written in REBOL and shows off its strengths. Unfortunately it also puts them off on their own little island.

即将到来的REBOL 3有望解决许多这些问题，除了最后一个。

我讨厌内梅尔的五个方面:

局部函数不能让步 编译lambda的能力有时取决于它是否内联 元组的值/引用类型语义不一致 数组下标和类型参数之间偶尔会出现歧义 缺乏普遍采用
