*raises hand* This makes sense to me, but seeing as the other discussion
going on at this moment is about SCALAR refs vs. HASH refs, might I posit a
recommendation? What if there were AsHash and AsScalar calls? The two of
them would be used to force a ref of a given type to the other type. Things
would have defaults (as described in the rest of your stuff), but users
could always do things like:
my $b = Wx::Button->new( ... )->AsHash;
$b->{foo} = 1; $b->{BAR} = 2;
That would let people override the defaults on a per instance basis. I'm
guessing there would be little use for the AsScalar call, but somebody might
find it useful sometime:). The AsHash call would do all of your normal hash
tracking stuff. Also, FindWindow might have alternate variants
FindWindowAsHash and FindWindowAsScalar that would do the right thing
without the additional overheard of building the object and converting it.
Is this doable? Does it make any sense? It might reduce all these
arguments between people who want things one way or the other.
