They're most likely bugs. Since May, Pugs has been halfway towards
getting a new MO core.
<http://moritz.faui2k3.org/irclog/out.pl?channel=perl6;date=2007-05-17#i_18608>
Not everything has been working since then, and likely won't until the
other half is committed. #perl6 people might be able to fix minor
flaws, but there's general hesitation towards fixing things that might
be superceded by the new MO machinery.
