INTERCAL可能是最奇怪的语言特征的最佳汇编。我个人最喜欢的是COMEFROM语句，它(几乎)与GOTO相反。

COMEFROM is roughly the opposite of GOTO in that it can take the execution state from any arbitrary point in code to a COMEFROM statement. The point in code where the state transfer happens is usually given as a parameter to COMEFROM. Whether the transfer happens before or after the instruction at the specified transfer point depends on the language used. Depending on the language used, multiple COMEFROMs referencing the same departure point may be invalid, be non-deterministic, be executed in some sort of defined priority, or even induce parallel or otherwise concurrent execution as seen in Threaded Intercal. A simple example of a "COMEFROM x" statement is a label x (which does not need to be physically located anywhere near its corresponding COMEFROM) that acts as a "trap door". When code execution reaches the label, control gets passed to the statement following the COMEFROM. The effect of this is primarily to make debugging (and understanding the control flow of the program) extremely difficult, since there is no indication near the label that control will mysteriously jump to another point of the program.

一般来说，弱类型。

C:

printf("%c\n", 'a' + 3);

PHP:

echo 5 + "3";

还有太多其他语言。

C和c++中的三联体。

int main() {
   printf("LOL??!");
}

这将打印LOL|，因为trigraph ??!转换为|。

BrainFuck语言。真的是这样!

这并不奇怪或令人惊讶，但这让我总是说WTF:

语法或标识符名称的大小写敏感性。

大多数具有它的语言似乎只是因为C具有它。这样做没有什么好的理由。

不久前，当我在CS课上第一次发现C语言时，看到指针的行为方式是非常奇怪的。我们只是编写程序并猜测它会做什么，直到它们得到正确的行为
