Still would be able to do it with `use strict'. My proposal isn't going to
replace it! As it didn't replace the default global variables! As I said, I
don't want you to use it or even like it, I'm only wanting YAWTDI.

Actually, I think sometimes it can be done with -w (``Variable xyz used only
once, probably spelling error'').

OK. Fine to me. Under `use strict' it actually would be already an error.

I'm fond of having an alternative to it, ie. `use scope'. I don't want it by
default, as I don't want it to replace `strict' either. It would only be
there for anyone decide if he would or wouldn't use it.
As to turn on by default, I actually don't think making one of this things
default would be good, because it would make one-liners and small quick and
dirty scripts some harder to write. For longer scripts and modules (that
already are many lines long), writing one or two more lines isn't expensive
at all...
