perl - 为什么 Perl 中有这么多 "magic"？

Question

翻阅perlsub和 perlop联机帮助页我注意到那里有很多对“magic”和“magical”的引用(只需在其中搜索“magic”即可)。我想知道为什么 Perl 对它们如此丰富。

一些例子:

print ++($foo = 'zz')            # prints 'aaa'       
printf "%d: %s", $! = 1, $!      # prints '1: Operation not permitted'
while (my $line = <FH>) { ... }  # $line is tested for definedness, not truth
use warnings; print "0 but true" + 1  # "0 but true" is a valid number!

当 Perl 功能被描述为“神奇”时:

It means that that feature is implemented by NBA star Magic Johnson. Whenever Perl executes "magic", it is actually sending an RPC call to a remote receiver implanted in Magic himself. He computes the answer, and then sends a return message. The use of Mr. Johnson for all the hard parts of Perl provides a great abstraction layer and simplifies porting to new platforms. It's way easier than, say, the Apache Portable Runtime.
