Milestone:  To Be Determined              |  Component:  Python
  Version:  Boost 1.53.0                  |   Severity:  Problem

------------------------------------------+---------------------
 When I pass a numpy integer (or really any object that's not exactly a
 PyIntObject) to a BPL-wrapped function, I get errors like the following:

 {{{
 ArgumentError: Python argument types in
     CLAllocator.__call__(CLAllocator, numpy.int64)
 did not match C++ signature:
     __call__((anonymous namespace)::cl_allocator {lvalue}, unsigned long)
 }}}

 It would be great if, instead of checking for exact types, Boost.Python
 could use obj.__index__() or obj.__int__() to just get the integer value.
