Synopsis

Documentation

class Partial Source

Nullary type class to mark partial functions, e.g. head.

Instances

Tag PartialTag => Partial Source

data PartialTag Source

Prefer partial. However, if you want to disable Partial wholesale, make an orphan instance of Tag for this type. NEVER put an instance of this in a library.

partial :: (Partial => a) -> a Source

Accept the possibility of partiality.
