Documentation
class PatternFrom a b where Source #
Turn a term into a non-linear pattern, treating the free variables as pattern variables. The first argument indicates the relevance we are working under: if this is Irrelevant, then we construct a pattern that never fails to match. The second argument is the number of bound variables (from pattern lambdas). The third argument is the type of the term.
