Answer 1 · 2019-09-28T18:44:41.000Z

Is that for TIO? Any reason to use niecza there instead of Rakudo?

Answer 2 · 2019-09-28T19:20:43.000Z

@vendethiel TIO has both https://tio.run/#perl6 (Rakudo) and https://tio.run/#perl6-niecza right now.

Answer 3 · 2019-10-08T17:02:22.000Z

Niecza hasn't had much love since 2013. I'm not sure there's really a need for its availability?
