Okay, so 'd' then should be considered a conversion operation, whilst the others should only work if the object is actually an integer type (which is implied by specifying __index__). In other words - if %d or %u is specified, try __int__, then __index__ (according to the docs, u is obsolete and identical to d) - if %i, %o, %x, %X, or %c is specified, try only __index__ Agreed?

Okay, so 'd' then should be considered a conversion operation, whilst the others should only work if the object is actually an integer type (which is implied by specifying __index__).

In other words

  - if %d or %u is specified, try __int__, then __index__
    (according to the docs, u is obsolete and identical to d)

  - if %i, %o, %x, %X, or %c is specified, try only __index__

Agreed?
