# Documentation

data Unfolding Source

Records the unfolding of an identifier, which is approximately the form the identifier would have if we substituted its definition in for the identifier. This type should be treated as abstract everywhere except in CoreUnfold

exprIsConApp_maybe :: InScopeEnv -> CoreExpr -> Maybe (DataCon, [Type], [CoreExpr]) Source

Returns `Just (dc, [t1..tk], [x1..xn])` if the argument expression is a *saturated* constructor application of the form `dc t1..tk x1 .. xn`, where t1..tk are the *universally-qantified* type args of `dc`
