There was a problem hiding this comment.
I renamed this file from any.md to dynamic.md since it now contains tests for type[Unknown] as well as type[Any]. They're not different enough to justify a separate test file for type[Unknown], I don't think.

Summary
type[Unknown]andtype[Todo]should be considered assignable to alltype[]types, just liketype[Any]. Currently we do not treat them as such.type[Any]should be considered assignable to instances of subclasses oftype. Currently we only consider it assignable toInstance("builtins.type"), and do not consider it assignable toInstance("abc.ABCMeta")-- butABCMetais a subclass oftype.Test Plan
New unit tests and mdtests added. They fail on
main.
