Drop var constraint not solved

[zilinc]

To compile

type RbtConsumeF k v acc obsv = RbtElemAO k v acc obsv -> acc
type RbtCondF k v acc obsv = (RbtElemAO k v acc obsv)! -> Bool

rbtFTrue: all(k:< DS, v :<DS, acc, obsv). RbtCondF k v acc obsv
rbtFTrue _ = True

I got:

Leftover constraint!
Drop acc
   in the 1st alternative _
   in the definition at ("rbt.cogent" (line 91, column 1))
   for the function rbtFTrue
Leftover constraint!
Drop obsv
   in the 1st alternative _
   in the definition at ("rbt.cogent" (line 91, column 1))
   for the function rbtFTrue

I don't think it's the same bug as #29, as type arguments are applied while calling rbtFTrue.

Can you post a full example? I tried to compile this file:

type RbtElemAO k v acc obsv
type RbtConsumeF k v acc obsv = RbtElemAO k v acc obsv -> acc
type RbtCondF k v acc obsv = (RbtElemAO k v acc obsv)! -> Bool

rbtFTrue: all(k:< DS, v :<DS, acc, obsv). RbtCondF k v acc obsv
rbtFTrue _ = True

And it worked fine.
