510f3c0e40 Added logic to report a diagnostic if an instance variable is assigned only via an augmented assignment expression. 2021-09-22 10:21:24 -07:00
Eric Traut
1024fbfa72 Changed type evaluation behavior for protected instance variables (those that begin with a single underscore) and are assigned a literal value. Previously, the literal type was retained if the reportPrivateUsage was enabled. This caused various problems. It was a bad idea because type evaluations should not differ based on diagnostic reporting switches. 2021-09-22 10:20:32 -07:00

Eric Traut
af4deba83d Fixed bug that resulted in false negative when bidirectional type inference involved an "expected type" of Any and the type being evaluated was a call expression that returned a generic object as a return value. 2021-09-20 08:08:28 -07:00
Eric Traut
e49e0ff6d9 Fixed false negative error in parser where it did not correctly detect a syntax error when a walrus operator was used in a ternary operator condition expression. 2021-09-19 22:48:44 -07:00

232f22e13b Added support for ParamSpec matching when used within a callback protocol. PEP 612 is unclear on whether this should be supported, by pyre (the reference implementation for the PEP) does support it. 2021-09-19 14:21:31 -07:00
