utils.to_primitive still tripping up on some objects ...

[Sandy Walsh]

Recent changes were made to utils/to_primitive to support classes/instances, but json still trips up over things like built-ins, modules, etc.

Seems like "all" is causing grief, although it is handled by inspect.isbuiltin()

I think the "ERROR" part of this trace is a different issue.
