Edwin Brady	97ee3d4cd3	Check LHS arguments are polymorphic enough ... We already did this, but missed a few cases due to the way arguments are elaborated. So now, when checking an LHS, we don't allow LHS argument types to be inferred from the pattern, but rather they must be inferred from elsewhere. To do this, we keep track of the constraints which would be solved when inferring the type, and make sure they don't solve any new metavariables. Fixes #1510, and also now gets the error location right as a bonus!	2021-06-13 13:31:40 +01:00

Edwin Brady	7d235272e3	Remove redundant converstion checks in Pi types ... We've already checked argument and scope types, so only need to check mulitplicities. This saves a lot of repetition when checking lambdas.	2021-06-10 12:19:41 +01:00
Guillaume ALLAIS	31a5175a02	[ re #1031 ] Disallow ? patterns on the LHS ... We do this during desugaring because elaboration may insert valid `?` values on the LHS (e.g. when elaborating things that cannot be pattern-matched on and should be checked to be forced).	2021-05-20 10:23:00 +01:00
