It's now possible to run a native-mode Perl 6 program (i.e. using Parrot rather than Haskell as the interpreter). See http://use.perl.org/~pmichaud/journal/35272 for the details. There are probably a lot of rough edges, (I don't know exactly what proportion of the spec is implemented), but it can say "hello" and tell you that 1 + 1 = 2.
