Has anybody involved in parrot taken a look at SableVM? It's an
interesting Java VM, done as a doctoral thesis.
http://www.sablevm.org
The thesis covers some interesting optimizations(don't know if any could
apply to parrot).

In my ongoing quest to understand the possibilities (and possible
limitations) of parrot, here's another one. ;-)
How close a mapping can there be between regular (x86 in this example)
assembly (as generated by c-compilation) and pasm?
I can't figure out if the stack ops can approximate this kind

Parrot assembly supports inline strings, but are there any plans to have
it support a distinct .string (or similar) asm section? The main benefit
would be easier compatibility/portability with existing assembly code
generators. Is anybody aware of an existing assembly format that doesn't

On a whim I took the primes.pasm example from the parrot examples page

A number of the language examples in parrot seem to not work as well as
they once might have(or should).
The learning curve to get familiar something like parrot is much easier
if things like this just work. So, if anybody cares, here's the list of
issues I ran into in the languages directory:
