type supports len()

------------------------------------------+--------------------------------
It would be helpful for enums inheriting {{{Choices}}} with a data type
supporting {{{len()}}} to be able to compute {{{max_length}}} by
themselves.
This would make the definition of field's {{{max_length}}} easier as well
as automatically create a new migration when deleting/adding members which
would change the {{{max_length}}}.
If the data type does not support {{{len()}}, it could raise
{{{TypeError}}} (same exception raise by {{{len}}}) something like :
{{{
raise TypeError("Can only compute max_length on data type supporting
len()")
}}}
I can do the patch if this feature does make sense to you.
