coercesj
to a function; i.e. it inserts a coercion intoj
, if needed, in such a way it gets as type a product; it returnsj
if no coercion is applicable. resolve_tc=false disables resolving type classes (as the last resort before failing)

coercesj
to a type; i.e. it inserts a coercion intoj
, if needed, in such a way it gets as type a sort; it fails if no coercion is applicable

coercesj
to its base type; i.e. it inserts a coercion intoj
, if needed, in such a way it gets as type its base type (the notion depends on the coercion system)

coerces the Cases patternpat
