Documentation
pprUncovered :: Nabla -> [Id] -> SDoc Source #
Pretty-print the guts of an uncovered value vector abstraction, i.e., its components and refutable shapes associated to any mentioned variables.
Example for ([Just p, q], [p :-> [3,4], q :-> [0,5]])
:
(Just p) q where p is not one of {3, 4} q is not one of {0, 5}
When the set of refutable shapes contains more than 3 elements, the additional elements are indicated by "...".
