* Fix crash in goto-def on `@override`
When the base type is not defined, getDefinitionFromOverriddenMember
will have its type as errorType, which has no symbol. The error handling
previously only handled the case of no baseType at all -- which I'm not
sure ever actually happens.
* Improve checking
1. getTypeAtLocation never returns undefined, only errorType, so check for that.
2. Return directly after missing baseTypeNode instead of continuing to return later.
* Experiment with making goto-def on `override` more consistent
* Unify static/instance node->symbol->type path
* Make getSymbolAtLocation support class expressions
and parenthesized expressions
* Revert "Make getSymbolAtLocation support class expressions"
This reverts commit 4c1b031355.
* fix semicolon lint
* Include type parameter defaults in contextual typing
* Add tests
* Add additional an test for instantiating contextual signature using default type param (#51002)
* Update comment
