From http://perlgeek.de/en/article/mutable-grammar-for-perl-6

What I could understand is that since the grammar of Perl 6 is written in Perl 6, One can override the grammar and change some of the syntax itself? Am I right if say this?

What level of flexibility would that be? I mean one can probably change keyword names like 'for' could be changed to 'from' , Or the sigils could be interchanged like '$' for '%' and viceversa,Converting all the keywords to capital letters etc. What other possibilities can be achieved and upto what level is it available

This seems to be a very powerfull feature which no other language is having currently.
