Clifford.pm6 module currently fails due List.MixHash coercer
fails to delete the key when the final weight ends up being zero:
<Zoffix> c: 2017.05,HEAD dd (0 => 1, 0 => -1, 0 => 0, ).MixHash
<committable6> Zoffix, ¦2017.05: «().MixHash» ¦HEAD(abfb52b):
«(0=>0).MixHash»
The issue only appears to happen the weights change from non-zero to zero while
going through Pairs:
<Zoffix> c: 2017.05,HEAD dd (0 => 0, ).MixHash
<committable6> Zoffix, ¦2017.05,HEAD(abfb52b): «().MixHash»
<Zoffix> c: 2017.05,HEAD dd (0 => 0, 0 => 0,).MixHash
<committable6> Zoffix, ¦2017.05,HEAD(abfb52b): «().MixHash»
