Satisfy that maps #186

Closed j-mie6 closed 11 months ago

j-mie6 commented 1 year ago

Instead of satisfy(f).map(g), it might be nice to support a partial function satisfy { case x if f(x) => g(x) } style of combinator, this can be then optimised and replace the SatisfyExchange instruction with a const function or something like that. Worth exploring! It might be possible to do this as an overload, not sure.

Overload isn't possible, one of the following names will work well: satisfyMap, mapSatisfy, satisfyAs.
