What's Changed

new diagnostic rule - reportEmptyAbstractUsage

pyright only reports an error when you instantiate an abstract class that has unimplemented abstract methods. but a class that explicitly extends ABC (or uses ABCMeta) with no abstract methods can also be instantiated, and pyright has no issue with that:

from abc import ABC

class Foo(ABC):
    """abstract class with no abstract methods"""

foo = Foo()  # no error

but the author of the class likely intended this class not to be used directly, and instead subtyped. so if a class extends ABC but defines no abstract methods, instantiating it is likely unintentional.

the reportEmptyAbstractUsage rule flags such instantiations. see the docs for more info.

implemented by @​KotlinIsland in DetachHead#1748 (some fixes by @​detachhead in DetachHead#1766)
