Programming in Perl Style

這是 ABC Perl Programming 之後的第二部分。名稱改成現在這樣是因為一本書，叫做 Higher Order Perl 。這本書的作者提到很多 Perl 的程式員在用 Perl 寫 C 的程式。這是一件很不幸的事情。當然了，所謂高手可以用任何方法做任何事情。但是，既然是在學習一個語言，至少要有三分樣吧。

下面是 Higher-Order Perl 這本書前言的第一段。

A well-known saying in the programming racket is that a good Fortran programmer
can write Fortran programs in any language. The sad truth, though,
is that Fortran programmers write Fortran programs in any language whether
they mean to or not. Similarly, we, as Perl programmers, have been writing C
programs in Perl whether we meant to or not. This is a shame, because Perl is
a much more expressive language than C. We could be doing a lot better, using
Perl in ways undreamt of by C programmers, but we’re not.
