Good god - its only been a few hours. Give people a chance ;-)
The thing I find most pleasing is that we'll get XS support (from the Ponie FAQ):
The guts of Perl 5 will be ripped out and made to work using Parrot PMCs rather than Perl 5 Sv structures, which will mean it will be compatible with Perl 6 . Any XS-based code that uses the published Perl 5 API should work fine without any problems.
XS code was going to need rewriting with previously discussed P5/Parrot layers so this is excellent news.
