You just need to register on the issue tracker. On bugs.python.org, there is a "register" link under the "User" section on the navigation bar.

In the issue (http://bugs.python.org/issue24270) Tal wrote

[...] """ Should we just leave things as they are and remove mention of complex values from the PEP (it isn't mentioned in the docs)? """ I'll update the PEP.

If we're going to add a separate complex version of isclose() to the cmath module, then you should probably leave the PEP as it is.

While we're on the subject of the PEP, is there a reason that the cmath version should accept complex values for the tolerances? I'd expect it to accept only floats, and I think that allowing complex values would be more confusing than useful.
