So I'm playing around with Docker files (Perl 5 ATM) and one thing I'm getting quite into is trying to keep them small. An important part of this is deleting any extraneous caching info built up during the build, preferably as part of the RUN step to get intermediate layers small. (So with Perl5 a

Re: How to pin down a bug in Rakudo?
