Resolves #7074. Now that we always use
@dataclass
instead ofdatatype
, and replacedCollection.of(T)
withCollection[T]
, it is safe to removedatatype()
.We also remove
TypedCollection
as it is no longer in use. Instead, we use explicit type hints likeTuple[str, ...]
orCollection[T]
.We avoid a deprecation cycle because V2 engine code has always been experimental.
Keeps
util/objects.py
We still keep
TypeConstraintError
,Exactly
,SuperclassesOf
, andSubclassesOf
. These are used widely in the codebase and have no standard library equivalent. They also do not seem to cause problems for MyPy.
