Re^2: version string oddities (-bug)

Note that v-strings aren't required to demonstrate this oddity.

> perl -wle 'print -"abc"'
-abc
> perl -wle 'print -"/abc";'
Argument "/abc" isn't numeric in negation (-) at -e line 1.
-0

Which I first considered a bug in unary minus (thinking it should only act this way on bare words), but I think it is a reasonable choice if it is intentional and documented (it just isn't how I had the feature explained to me).

Hmm, check this out: `% perl -le'print -"-aaa"' +aaa % perl -le'print -"+aaa"' -aaa` [download] That's highly unexpected to me.	[reply] [d/l]

Looks like you don't even need the quotes: `$ perl -le 'print -aaa' -aaa $ perl -le 'print -+-aaa' +aaa` [download] You can't put "--aaa" because Perl thinks it's a decrement.
