If telling my opinion is preventing us to become friends, i'm sorry for
I heard "some" people to complain about the ./method() syntax too.

Maybe per .-file in the home-directory, like .vimrc ...
But i don't think that pushing everyone into his own language is the
purpose of designing a new one.
Also, i would be VERY curious how that 'self' module looks like.
Is there already a spec that describes how to change the parser on the
fly in such a module?
And how many people, who dislike the ./-syntax will be actually able to
write such a module? Or a module that works around another
syntax design quirk in perl6?
If the majority really wants ./, okay, i am fine with it.
My own opinion is, that ./ doesn't fit into the language very
much, at least not with a 'but it looks like shell
programming'-argument. Perl6 isn't shell programming, and ./ has a
completly different meaning (at least for me, and others i heard about
this issue) in perl.

Java-people also invent new tools to ease the pain of writing java-code.
But Perl6 isn't as static as Java (of course) and will mutate into
a custom language for any dedicated Perl6 programmer.
It will be hard/easy to read someones elses Perl6 code regardless of the
I don't think that this kind of syntax-translation is so very easy...
and what about a perl6 program in a cvs. You probably want to change
the code you read...

I would be completly fine with $?SELF.method () as default.

I wanted to express my fear that perl6 might
push me and others to write their own language plugin
to work around suboptimal design in perl6.
