Rules, like regexes, are essentially language neutral. So that's

Yes, I think that's the way to go, as well as :coerce for exp

May or may not be of use, but Larry's view sounds a bit like reconcilling the

I'm glad to report the soon-to-be-released Pugs 6.2.11 now targets
Parrot with the new calling convention and lexical pad syntax.
However, the explicit demand on a "newclosure" runtime call makes
package-scoped subroutines awkward to generate and use -- please see
this journal entry for details:
(More brain dump.)
"Context" is implemented as type coercion calls, implicitly inserted
by the compiler.
There are five types used in these calls. The "..." below denote
the positions where these contexts typically occur, using common
Perl 5 operations as examples:
Void # ...;
This is a brain-dump of how container types and contexts work in the
new Pugs runcore.
Assuming everything other than an explicit method call is subject to
MMD, we have this desugaring:
# Sugared syntax
${$x} = 5;
# Desugared syntax
&infix:<=>(&circumfix:<${ }>($x), 5);
It's str

we have a fast, pure Haskell implementation of basic Perl 6 Rules
