Another thing I didn't mention is that that binds both the variable

Would c! be an option?

In current Perl 6: Yes, because infix ! does not exist.
But several people want ! to be a chainy none() constructor, and this
would destroy a dream.

Speaking of which the advantage of, say, « over is that the former is
_one_ charachter. But Y, compared to ¥, is one charachter only as well,

What about something like:

Then you get

Not exactly pretty though. c\T
Actualy i think ^ might be my favorite so far.
sub sametype (^T $x, ^T $y) {...}

You seem to be forgetting that we do have the longest token rule. So,
the only way this destroys a dream (and likewise, the only way c|
doesn't work), is if you have the poor package or class name c and you
insist on writing c|d or c!d without

Speaking briefly, Unicode is the way of the

support for it. Perl 6 is a language of the
