Description of the change
Motivation for this change is to give users a more ergonomic alternative to:
purescript-lists/src/Data/List.purs
Lines 619 to 620 in 6d8e30e
We can currently do a little better with NonEmpty's
:|
operator:But it's even nicer with this change, which introduces the
:||
operator forcons'
.I'd ideally like to reuse the
:|
operator, but that leads to complications since we then can't use that operator for pattern matching anymore (it's equivalent toNonEmptyList (NonEmpty x xs)
. The new version is no longer a simple data constructor of 2 arguments. We'd likely need to enable Pattern Synonyms for that to work.Checklist:
