Well, not *that* compatible :-)

Point taken.  But it's not so much about comparing new candidates
against already existing parts in size than having to choose among
several candidate modules for inclusion, and their usefulness/size
ratio.  Also, what goes in cannot be taken out.  Ever.  Therefore
I tend to favor stable (no jokes about my signature quote, please)
modules (Inline was an exception since it looked, and still looks,
so ingenious an idea -- but the author of Inline quite wisely chose
not to accept my "invitation".)

I'm sorry to sound blunt that discussion about perl 6 internals is
best to have in the perl6-internals mailing list.  There's a reason
we decided to start the Perl 6 project, after all...  many of the
solutions that will make sense for p6 won't make sense for p5,
and vice versa.
