By this reasoning - why have a shortcut to any of the invocants at all? This
thread has headed in the direction of finding a way to figure out how to call
methods on the invocant without using the signatures name. On a method call
without a signature and without invoking Perl5isms there would not be a "way
back" to the invocant once you enter nested block.
The point of all of this discussion is to not have to set $self to anything.
The argument for .meth as opposed to $self.meth of $_.meth was that .meth was
clear enough to mean the current topic and was a nice huffmanization.

That works great - so long as I specify the signature. I'm lazy, I don't want
to type the signature all the time. Consider:
method foo {
for 1 .. 10 {
$^.method(.sqrt);
}
}
Still pretty readable. I kind of like $^1 too which seems to behave like
$^variable quite nicely. I guess that $^1 should actually be $^0 so that we
are properly zero indexed. At this point - it sort of looks like Perl5's
$_[0] except now $^0 is just an alias and and it gets all of the attributes
given by the signature (should a signature be given) - plus we don't have to
deal with the [EMAIL PROTECTED] array.

If I didn't like typing the signature - why would I want to type all of that
code to bind the variable? I'm lazy. The signature wouldv'e been shorter.
That looks Perl5ish.

Same argument as the last with a different "aliasing."
Yes, I know there "can be" a "way back." In this thread, none of the examples
give one using existing Perl 6 syntax. They are all proposing new ways.
This is one more.
