It wasn't activated because you didn't "use assertions" at all.
And BTW I think that 'use assertions' without an import list should be
disallowed.
But I agree that having a bare -A equivalent to '-A.*' would be nice.
I have one concern :
if you say "use assertions qw/foo bar/" you need to pass -Afoo,bar to activate
the assertions in the corresponding block. I'd have expected that -Afoo and -Abar
work too (i.e. that assertion groups are or-ed, not and-ed).
