Imagine how I felt when Perl 4 came out, with all that silly binary I/O
stuff! I had no idea what Larry had
What are the restrictions on "is rw"? For example, can it be used with
variables of a particular type? If so, does the parameter passed have to
already be that type? What does this do?
sub process(int $i is rw) { $i++ }
my $x = "10";
process($x);
Does C<$x> become 11? That would requ

Its good
I'm thinking XS thoughts because we're going to need a few external
things at SOME point It would be so nice if Perl 6's XS was part of
the language, rather than an external pre-processor.
Something like:
module somesuch;
use External (language=>"C");
sub chdir(string $path //= $

Of course, in Perl 6, they'd return a superposition of all possible

in the core language. Hyper operators may need lookahead.
Place holders may need lookahead. User defined rules

Perl already needs infinite lookahead. Anyways, most people
don't care whether a grammar is ambiguous or not -- if we did,
natural human languages would look very different.
