3671	Add partitioning functions to Data.List	holzensp		"The functions `take` and `span` have recursive equivalents `takeRec` and `spanRec` that apply the same function to the remainder, i.e.
{{{
takeRec i xs = let (hs,ts) = splitAt i xs in hs : takeRec i xs
spanRec p xs = let (hs,ts) = span    p xs in hs : spanRec p xs
}}}
and the more generic version of `take`:
{{{
genericTakeRec i xs = let (hs,ts) = genericSplitAt i xs in hs : genericTakeRec i xs
}}}
These functions, to me, are in the same league as `partition` and `group`, can be added with little chance of nameclashes on functions with a different meaning and are not named compositions."	proposal	closed	normal	Not GHC	libraries/base	6.12.1 RC1	wontfix	Data.List		Unknown/Multiple	Unknown/Multiple	None/Unknown
