It was Friday, May 09, 2003 when David Dyck took the soap box, saying:
:
: This really isn't resolved, as
: perldoc -f require states
:
:
: If EXPR is a bareword, the require assumes a ".pm"
: extension and replaces "::" with "/" in the
: filename for you, to make it easy to load standard
: modules. This form of loading of modules does not
: risk altering your namespace.
:
: but it doesn't mention .pmc.
Now it does, see patch below.

+Now that you understand how C<require> looks for files in the case of
+a bareword argument, there is a little extra functionality going on
+behind the scenes. Before C<require> looks for a "F<.pm>" extension,
+it will first look for a filename with a "F<.pmc>" extension. A file
+with this extension is assumed to be Perl bytecode generated by
+L<B::ByteCode|B::ByteCode>. If this file is found, and it's modification
+time is newer than a coinciding "F<.pm>" non-compiled file, it will be
+loaded in place of that non-compiled file ending in a "F<.pm>" extension.

You can also insert hooks into the import facility, by putting directly
Perl code into the @INC array. There are three forms of hooks: subroutine
references, array references and blessed objects.
