Not here, no. How is that.

I called him a liar in another thread, but about his characterization
of Perl::Types implying it was vaporware. We've discussed this.

Oshun is clearly in flux, have you seen Curtis' keynote? He says
as much.  Maybe not in those words, but it's almost entirely

Here's the part of the talk that Curtis presented as a budding
thought, and which made it clear to Will (and I) that Perl::Types
needed to be brought up now. Not later. Will and I were both sitting
in the room watching the talk. You will hear at some point in the
video, Will is commenting to Curtis that Perl already has a type
system. That type system is not Perl::Types, but Perl::Types takes
advantage of the existing "types" system. Therefore it's a hugely
missed opportunity to ignore that it exists. And it is real.

It's a good talk, I suggest you watch the full thing.

I follow the conversations on their Github discussion forum.

Had not seen the "spec". But even if I had, it just confirms what
I was saying. This is not knock against the project, it's in a very
early phase.  That's why Perl::Types is getting brought up now.
The Oshun spec, says:

    =head1 STATUS
    This is very early alpha code, designed to prototype an idea that might one
    day be a core feature of Perl.
    Every aspect of this module is subject to sudden and radical change,
    from the check syntax itself, to the names of the various checks,
    to their essential behaviours, features, and limitations.

Thank you for pointing out Curtis shared the link.
