Esteemed Monks,

I have a script foo.pl and a module Bar.pm both located together in a directory /my/stuff . In foo.pl I have: 

use Bar;

...etc

If my present working directory is /my/stuff and I run foo.pl everything is great. If my pwd is /somewhere/else and I execute /my/stuff/foo.pl I fail like so this: 
Can't locate Bar.pm in @INC (@INC contains: /usr/local/lib/perl5/5.005
+03/sun4-solaris /usr/local/lib/perl5/5.00503 /usr/local/lib/perl5/sit
+e_perl/5.005/sun4-solaris /usr/local/lib/perl5/site_perl/5.005 .)

OK, so I could fix this by putting Bar.pm in one of the @INC dirs or by adding /my/stuff to the PERL5LIB ENV var prior to running the script. However, for several reasons, it would be much easier for me, and I would prefer to, modify foo.pl. Since the use statement is done at compile time, there is nothing I can do in the foo.pl script to keep the use Bar syntax if Bar.pm isn't already in the @INC.

I can replace  use Bar; with  require "Bar.pm"; and this seems to work.

Question: what effects does using 'require' instead of 'use' for a module have?
