I think a heirarchy is a good idea for namespacing in general. I've
always wanted to be able to tie namespaces in Perl 5. It would only
make sense that if I tie Foo::, that Foo::anything:: would also go
through that tie to get the anything:: stash.
What do you mean by "tie" here? Are you talking

If you're on OS X 10.3, I unbroke (sort of) the dynaloading code, so

The set_integer_native() vtable method of arrays is implemented
inconsistently. The old historical way in Array was to set an initial
size. My implementation in SArray OTOH only reserves the needed store,
but doesn't change the element count.

set P0, 2
set I0, P0 # SA

I have just installed Fedora Core 1 on a Pentium 4 system, and various
tests are segfaulting when trying to invoke a compiler. I tracked it
down to Parrot_jit_build_call_func. If I undef CAN_BUILD_CALL_FRAMES
then all tests pass. Also, everything segfaults using parrot -j.
