Perl Programming/Keywords/use
The use keyword
edituse imports some semantics into the current package from the named module, generally by aliasing certain subroutine or variable names into the calling package. It is exactly the same as
BEGIN { require Module; Module->import( LIST ); }
with the exception that Module must be a bareword.
Syntax
edit use Module VERSION LIST
use Module VERSION
