in thread What happens when you load the same module twice?

Because calling 'use File::Basename();' tells the compiler to import an empty list -- in other words, do not import anything. The issue at hand is that File::Basename and File::Basename are both trying to import subroutines into the main:: namespace by default.

    So the import is the part that is creating redifined errors not the processing of the module file?

    No. It has nothing at all to do with importing names twice. Not convinced? Run this code:
    #!/usr/bin/perl use strict; use warnings; use File::Basename (); # Not calling import! BEGIN {delete $INC{"File/Basename.pm"}}; use File::Basename (); # Not calling import! __END__ Subroutine fileparse_set_fstype redefined at /usr/lib/perl5/lib/5.8.6/ +File/Basename.pm line 157. Subroutine fileparse redefined at /usr/lib/perl5/lib/5.8.6/File/Basena +me.pm line 171. Subroutine basename redefined at /usr/lib/perl5/lib/5.8.6/File/Basenam +e.pm line 238. Subroutine dirname redefined at /usr/lib/perl5/lib/5.8.6/File/Basename +.pm line 251.
    Can we now please stop this myth that redefining subroutines has anything to do with import?
