deterministic operation |

documentation:
|
Tests whether both arguments evaluate to the identical currently unbound
variable (use with care!).
For instance,
identicalVar (id x) (fst (x,1)) where x free
evaluates to `True`, whereas
identicalVar x y where x,y free
and
let x=1 in identicalVar x x
evaluate to `False`
