idris-tmustache's Issues

Create monadic version of insert

Insert should be allowed to fail (e.g. if we don't want to override existing values):
For that to work, we need update with the type:

update : (TotalStrictOrder ltR, Monad m) =>
         (k : key) -> ({k1 : key} -> k = k1 -> Maybe (val k1) -> m (val k1)) ->
	 ExtendLT ltR l (Lift k) -> ExtendLT ltR (Lift k) u ->
         Tree ltR val l u n -> m (MayFit ltR val l u n)

Use `compareBy` instead of `the (Trichotomy ...) ...` everywhere

The idea of introducing compareBy was so simple, it took me weeks to think of it...

Port all of the calls to the (Trichotomy ltR x y) (trichotomy x y) to compareBy ltR x y.

Make `Tree.lookup` lazier

Just like trichotomy was too strict so is Tree.lookup which can lead to some type-level
computations getting stuck (e.g. uses of Set.elem).
