Pattern Synonym for Ratio
Data.Ratio
should export a simple pattern synonym that can be used by Safe
code.
infixl 7 :%:
pattern n :%: d <- n :% d where
n :%: d = n % d
It'd be much simpler to use than numerator
and denominator
, and pattern matching on it would turn into a regular pattern match, hopefully for free.
