Thank you for the report. However this is not a bug.

See conversation in https://irclog.perlgeek.de/perl6/2017-05-24#i_14629522

I also added[^1] docs for Mu.Capture, which is what the OP code is using, and
opened[^2] a doc Issue to ensure we have clear documentation on what public attributes
the types have (which is what ends up as the Capture via Mu.Capture)

The RT System itself - Status changed from 'new' to 'open'
