Unionize the duck types

An option to unionize the duck types.

a: float
reveal_type(a)  # float | int

I think a configuration option like duck_types with values of unionize, plain(#167) and standard

relates: #6

unionize
(verb): become or cause to become members of a trade union.

Are ducks eligible to join trade unions? And what does this have to do with your mypy fork?
