It's not. I was talking about Perl6::Gather, Perl6::Junction etc.: "pretty much anything except smart match [...], Class::MOP and Moose falls under the ... underused".
So Moose is not underused. But some of the other modules that draegtun cited are. It's disingenuous to cite some crazy module Damian wrote that nobody uses as an example of Perl 6 features in Perl 5.
I use MooseX::Declare, Perl6::Gather, Perl6::Junction and Regexp::Grammars in production regularly so on that basis my listing them is totally sincere.
However stating that I'm disingenuous to list them at all... is well a very disingenuous slant directed at me :(
