F841: unused local in 'with' statement with parethesised value does not converge

[addisoncrump]

This is a really specific one. The following snippet prevents Ruff from converging:

def e():
  with (input('>')) as f:
    print(1)

To trigger this, the value specified in the with must be parethesised and the with must not be in the global scope of the script.
