I put the subs that select the args, because I didn't want to restrict how args should be formatted. The '-4Me;And;You' thing was to show how extensible the module is. Not everybody is writing (for) POSIX syntax arguments. I do much work on Win32, in which case arg keys are supposed to be more like /something. I hope you get my point. Sure, there are many modules, but this is the only one (I have seen -- not like I work at Google, though) that doesn't think for you. I don't want to replace the programmer. You must choose which args go where, and that is why I put the choosers. GetOpt, you'll notice, is simply for one kind of command-line args. Thanks for the code!
