Hi, +1 (stating the obvious) Greetings, Joachim Am Samstag, den 15.03.2014, 00:16 -0400 schrieb Edward Kmett:
We removed the data type context from Data.Complex some time ago.
However, when we did so, we left the rest of the API in that module intact.
Many of the accessors in that module (should) work with much more general types now!
e.g.
realPart :: Complex a -> a
instead of
realPart :: RealFloat a => Complex a -> a
I propose we stop passing around dictionaries we don't need to methods that don't use them.
Concretely, I'm proposing we simplify the signatures of the following functions, which in the current API all unnecessarily take a RealFloat constraint that they don't use.
realPart :: Complex a -> a imagPart :: Complex a -> a conjugate :: Num a => Complex a -> Complex a mkPolar :: Floating a => a -> a -> Complex a cis :: Floating a => a -> Complex a
