That's unusable for at least Python and probably more HLLs as the

I'm not sure how any invocant can assume a Plural context anyway,
so this behaviour seems correct. Is it, though? :)

Sounds cool, but what about $n = 0; ?
Then it would be 0..-1, an empty range.

On behalf of the Pugs team, I am delighted to announce the release
of Pugs 6.2.3, with Parrot embedding, Perl 6 Rules support (via PGE),
an initial sketch of OO system. Multi-thread programming with
async/kill/join/detach is now supported as well.
Also of note are many new, working modules under
Thit has led to surprising results in Pugs's Net::IRC:

my $socket = connect($0, $1);
}
If $1 is a match object here, and connect() assumes Int on its second
argument, then it will connect to port 1, as the match object numifies
to 1

Juerd informed me today that .method should still means $_.method.
However, for the OO modules we're writing, there still needs to be a way
to invoke methods on the current invocant, when the invocant name has
been omitted from the method() declaration.
Currently Pugs has:
