If you want to clear out a package, you could do the following... 
sub ERASE_PACKAGE {
  # Call with "Package::Name"
  my $packname = shift;
  $packname .= '::' unless  $packname =~ /::$/;
  no strict "refs";
  warn $packname;
  my $package = *{$packname}{HASH};
  return unless defined $package;
  undef *{$packname . $_} foreach  (keys %$package);
}

Many caveats. It's not good for unusing a module. See the above comments about @INC. Also it won't remove exported symbols. So if you export function Pack::Foo::foo(), the symbol table that it was exported to will still have foo() available after it's been erased.

It can be useful for clearing out variables. I would only recommend it for situations such as that.
