c#中的“动态”。

因为智能感知、类型安全和决定论会随着“动态”关键字的第一次使用而立即消失，因此所有必须与RAD或python受害者一起工作的人的日子都被毁了。

对我来说，它绝对是INTERCAL中的PLEASE修饰符。 如果PLEASE出现的次数不够多，则认为程序不够礼貌，错误消息如下所示;如果太频繁，这个程序可能会被认为过于礼貌而被拒绝。

红宝石拖鞋。条件语句中的"…"和".."并不总是范围操作符:

(0..20).each do |x|
  if ((x%10) == 5)..((x%10) == 5)
    print "#{x} "
  end
end

(0..20).each do |x|
  if ((x%10) == 5)...((x%10) == 5)
    print "#{x} "
  end
end

这将输出:

5 15
5 6 7 8 9 10 11 12 13 14 15

. .检查每一遍的两个语句，…每次只检查“on”或“off”语句(取决于触发器状态)。它们是从awk和sed偷来的。

Matz在“Ruby编程语言”中写道:“人字拖是Ruby中一个相当晦涩的特性，可能最好避免……”

C# has a feature called "extension methods", which are roughly analogous to Ruby mix-ins - Essentially, you can add a method to any pre-existing class definition (for instance, you oould add "reverse()" to String if you were so inclined). That alone is fine- The "Weird" part is that you can add these extension methods, with a method body and everything, to an interface. On the one hand, this can be handy as a way to add a single method to a whole swath of classes which aren't part of the same inheritance tree. On the other, you're adding fleshed out methods to interfaces, essentially breaking the very definition of an interface.

Processing (processing.org)是一种基于Java的语言。简单来说，处理编译器是将特定于处理的语法转换为Java的Java预处理器。

由于语言的设计，它有一些惊喜:

Processing的类被编译成Java内部类，这会引起一些麻烦，比如私有变量并不是真正私有的

class Foo {
  private int var = 0; // compiles fine
}

void setup() {
  Foo f = new Foo();
  print(f.var); // but does not causes compile error
}

同样缺少draw()函数会导致事件处理程序不被调用:

// void draw() {} // if you forgot to include this
void mousePressed() {
  print("this is never called");
}
