@asvetlov my $0.01 for the future. What do you think about removing all the code form __init__.py? which may and probably will come as a breaking change.

We can have yarl/_url.py with all the stuff from current __init__.py and have single line with import like from ._url import URL in new __init__.py. IMO, Otherwise yarl has pretty bad public API.

[asvetlov]

Do you mean the number of internal names exposed by __init__.py?

[uwinx]

yes.

[asvetlov]

These internal names are not exposed by __all__, so the situation is not dramatically bad.
I'm +0 for the change (need to finish all pending PRs first)
