Ideally these should be done as the last part of https://github.com/exercism/perl5/milestone/1, else we end up doing work which will only end up having to be replaced.

EDIT: Clarification on when this should be done.

@mienaikage I found this project from https://github.com/tpf/perldotcom/issues/203#issuecomment-535099706 and it looks like there's some decent work to be done! I am confused by the milestone you reference in https://github.com/exercism/perl5/issues/249#issuecomment-467855118 - this issue is part of it! So should this issue be worked on yet or not? Also, are any of these blocked on #322? Thanks in advance for the clarification!

[m-dango]

Hi @cxw42, thanks for taking a look! This issue is the last one of the milestone, and each exercise can be worked on individually.

None of these are blocked by any currently open PRs. Some exercises already have open PRs with the tests updated, however I have not yet got round to adding solutions to them.

I'll take robot-name (edit #328)

It looks like Strain is generating now, and it appears that we have point-mutations which is new.
