I would like to say that:

I am one of those users which don't use Rakudo mostly because it is too damn slow.

Last month I switched back from Scala to Perl 5 one of my projects because the scala compiler/toolset was so slow I couldn't bear it anymore.

I don't mind about the incomplete parts, I could add them myself if required. Perl 5 is also quite incomplete in several ways.

Yea, I like implementing algorithms!
