We should also note that with Larry's recent work
on an "official" Perl 6 grammar [1], the syntax for
defining tokens may in fact be radically changing
from what pgc is currently using.. For example,
infix:<+> appears to be written as
token infix ( --> Additive) #+ +
{ <sym: +> {*} } #= +
and circumfix:<( )> is
token circumfix ( --> Term) #+ ( )
{ \( <EXPR> \) { @<sym>:=<( )> } {*} } #= ( )
So there could be more substantial pgc formatting changes
going on here than meets the eye. (I'm still figuring out
what all of the syntax means in the Perl-6.0.0-STD.pm
file.)
