What it means is, you can't prototype the thingy that could be
expected on the LHS of the =~, when function is open-ended,
because in foo($@\@), that final \@ never gets applied to any actual
argument.
More importantly, adding the LHS to the beginning of @_, as I proposed,
would be highly consistent (fwtw), since perl would rearrange
$x =~ foo( $a )
into
foo( $x, $a )
just the way it already rearranges
$x -> foo( $a )
into
foo( $x, $a )
(for certain types of $x, of course...)
Perl doesn't put the object at the end of the method's @_,
so I don't think it should in this case, either.
However, I feel that we're now arguing which end of the egg to break.
I'm sure Larry can figure out the best way to approach this issue.
