Perl6::Perl5::Differences — Differences between Perl 5 and Perl 6

Today I spent sometime on Perl 6, which is still on the way developing. Perl 5 is an excellent language, very powerful and is compatible with Linux/Unix quite well: shell, sed, grep, awk, …

However, Perl 6’s syntax seems quite strange, like a new language. I don’t think it is an easy way for Perl developers to transfer from Perl 5 to Perl 6. A lot of new stuff.

There is no any other language to do so big change from 1 version updated to a new version. Is it worth for Perl 6 to do so?
The question is: Currently Perl 5, Ruby, Python are already very mature and own domain markets; Perl 6’s effort worth or not?

The following is the comparing article between Perl 6 and Perl 6:
