I had already tried that, and it doesn't seem to work. I guess it is some
timing issue: $INC{P6C/Parser.pm} gets defined after P6C::Parser.pm is
loaded (I think).

to be an answer as I seem to think of them as
defining syntax for new commands that you are writing. (In this case, I do
not know where I would put the is parsed trait). I may be wrong and
macros in some form are the answer. Either way, I'd appreciate any
thoughts/answers/pointers on this.

No, obviously arguments. Okay, I see the problem. What you're missing

Oh, I see. Yes, I had missed that. Thanks for clearing that up.

In the case of:
@matrix = 1 2 3 4 5;
You need only add the type:
int @matrix = 1 2 3 4 5;
There is no string phase, or at least should never be.
The compiler can
pre-compute the list:
int
.
We probably do need the array version of the same problem frequently,
though:
@matrix... = 1 0 0 1;
At least we'd need it more frequently if we had it. A2 says that something
like this will be supported, come A9.

That's the problem with making them methods. Any such operational
definition is going to get you in

reasons, perhaps, as many common uses will parse arguments in standard
ways [though act in mind warping ways] ) ?

This is a rather silly question:
The code:
macro foo() { return {my $x = 7} }
foo;
print $x;
is equivalent to which of the following?
{my $x = 7}
print $x;
or
my $x = 7;
print $x;
Thanx,
abhi.
, then, that calls to user defined subs will need to end
with a semi-colon.
