To add to what Matthias said: C<use> is only HALF case-insensitive in
MacPerl.  It is neither a bug nor a feature, IMO, it kinda just _is_.

Consider the following module:

  package Foo;
  use Exporter;
  @ISA = qw(Exporter);
  @EXPORT = qw($x);
  $x = 'JAMPH';
  print 1;

Now, a script:

  use Foo;
  print $x;

This will print "1JAMPH".  But this script will print only "1":

  use foo;
  print $x;

This is simply because your use statement does not match the package name
in the file that was use'd.  The symbols in Foo are not imported, because
you are calling for the symbols in package foo.
