A look at Parrot 1.0

all that it will take to accomplish that is to show that language X running on parrot is better (faster, less resources used, fewer bugs, etc)

if that is true you will see conversions (after they get over the NIH syndrome ;-)

for perl it will be a good check against the mainline (there isn't currently any second implementation of a language spec, so with only one implementation, the implementation is the spec)
