We can, but I'd much rather have this particular case tested (and to make sure that it is, we'll close it with tests once the issue is resolved).
For example, here's this interesting bit: https://github.com/rakudo/rakudo/blob/master/src/core/core_prologue.pm#L2 : my class Pair { ... } # must be first for some reason I don't know if it's related to this issue, but Pairs are weird for some reason. Adding a test won't hurt for sure. On 2017-12-13 23:33:43, d...@zwell.net wrote: > Thanks for finding that. Can we close this duplicate bug?
