I do not think of Perl 6 as Perl, despite the naming and people involved. I believe that it is as easy to migrate from Perl 5 to another scripting language as it is to migrate to Perl 6.
Furthermore the last I heard, Perl 6 performance was a disaster story. And libraries + real world adoption is kinda thin on the ground. Therefore other scripting languages (particularly JavaScript and Python) are more compelling targets to migrate to.
Has this picture brightened in the last year or so?
