[issue1530559] struct.pack raises TypeError where it used to convert

[Mark Dickinson]

Mark Dickinson <dickinsm at gmail.com> added the comment:

I'd be open to re-allowing use of __int__ (and __long__) consistently for all integer packing codes in 2.7, as a temporary measure;  I'd really prefer not to allow this for 3.x.

What would make more sense, IMO, would be to allow use of the __index__ method (in both 2.7 and 3.x) to convert custom non-integer classes to integers before packing;  this is supposed to be the modern approach to creating integer-like classes that can be used as integers (e.g., in list indices).  Andreas, would this work for you, or do you need to be able to use __int__ and/or __long__?

Re-opening while we're discussing this.
