Well, a text filter remains the only way to change Perl 5's syntax --
but Perl 6 allows direct parser access, so we've been waiting lo these
eight years or so to see what happens there. There was also a
discussion some time ago about making Perl 6 syntax more array-
friendly. Larry didn't like our "(n)"-vs-"n" syntax for cutting out a
dimension in slices, and promised to think of something better -- but
I don't think he ever did.

Anyone know a solution to that?
I have an idea that is probably stupid and impractical, but I'll post
anyway and maybe someone can turn it into a good idea:
"Piddles" could be implemented as function references. A quick demo:
use PDL;
{
# This is a closure.
my $piddle = pdl [1,2,3,4,5];
$a = sub {
my $slice = shift;
$piddle->slice($slice);
}
}
print &$a("2:4") . "\n" ;
So, instead of writing $a(2:4) as in NiceSlice, you'd write
&$a("2:4"). This is a little more verbose, but requires no text
processing. The other drawback is that I have no idea how you'd
implement all the other piddle operations, but maybe someone who knows
something about Perl OOP knows.
Daniel.
