There's a somewhat significant mismatch between Perl 6's handling of
arguments and Parrot's handling of them; at the moment Rakudo
is following the Parrot conventions.
My guess at this point is that unless/until Parrot updates its
calling conventions, Rakudo will at some point generate most of
its subs as
.sub 'a'
.param pmc positional :slurpy
.param pmc named :slurpy :named
...
and then generate code to bind positional/named arguments to
local lexicals according to P6 conventions.

I suspect Parrot's MMD here, and since Parrot MMD is due for an
overhaul (pdd27) we'll probably accept this for a while.
Thanks!
