These sound great to me. If Haskell/2 is indeed open to such changes,
would also be possible to revamp the numeric modules? As a
mathematician, I get annoyed by such things as
* (+) and (-) being lumped in with (*) (doesn't anyone use vector spaces?)
* the function 'atan2' being mixed in with a bunch of operations very
specific to the floating point format in the 'RealFloat' class.
Same problem (though less serious) with 'quot', etc., and
'toInteger' in the Integral class.
* Superfluous superclasses: why are Show and Eq superclasses of Num?
Not all numeric types have decidable equality. Think arbitrary
(I saw Mechvelliani's Basic Algebra Proposal; it strikes me as being
too complicated for the task.)
