 原文： 12.6. What is the difference between use and require? The short answer is that something like: use Tk; is equivalent to: BEGIN { require "Tk.pm"; import Tk; } Hence the essential difference is that a mere require Tk; does not achieve the import of function/method names. The significance of this is that it allows one to call ->Button rather than having to call the fully qualified ->Tk::Button e.g.. For further details on this subject see man perlmod(1) or see Tom Christiansen’s document at: ftp://ftp.perl.com/perl/info/everything_to_know/use_vs_require 译文： 12.6 use和require有什么区分？ 简单的说，下面的语句： use Tk; 等价于： BEGIN { require “Tk.pm”; import Tk;} 所以，他们最本质的区分就在于，仅仅require Tk;语句并没有导入相应对象的函数（方法）名。这一点的意义在于，他就使我们能够直接使用诸如->Button的方法，而不必使用完全的包名- >Tk::Button等等。关于这个主题的更周详的讨论，能够参阅perlmod的手册，或能够参阅Tom Christiansen’s的文档： ftp://ftp.perl.com/perl/info/everything_to_know/use_vs_require |
