in reply to Devel::GetSymbols (fka Symbol::List)

I like it!

What I'd like to see in it too, was to have the possibility to further restrict contents of the result by a regular expression.

I know, you could do something like: 

@EXPORT_OK = grep /^[^_]/, Symbol::List::symbols('CODE');

to filter out subs beginning with '_', but as you do a grep in symbols() already, it would be more convenient to pass a regex.

    I don't think passing a regex adds much, because grep is so easy to use. And after all, it's what grep is for.
    @EXPORT_OK = grep !/^_/, Symbol::List::symbols('CODE');

    BTW, Symbol::List is not just for exporting :)
