Looking thru what exists of P6C I saw this in P6C/Nodes.pm:

Guilty as charged. My Perl6 is getting rusty...

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

I don't claim that we'd need that frequently.
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.

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.
it that the
absence of an explicit "is parsed" changes the behaviour (for efficiency
reasons, perhaps, as many common uses will parse arguments in standard
ways [though act in mind warping ways] ) ?
abhi.

It seems to me, then, that calls to user defined subs will need to end
with a semi-colon.
