Pyright warnings in strict mode: type is partially unknown for op.create_index

[AlexanderPodorov]

Example of op.create_index:
op.create_index(op.f('ix_token_expired_at'), 'token', ['expired_at'], unique=False)
warning: Type of "create_index" is partially unknown
reason (most likely): columns parameter has type Sequence[str | TextClause | Function[Unknown]]. Function generic is missing type parameter.

Expected behavior
No warnings produced

Versions.

Mypy is a bit leaking in some regards.
