Larry Hastings added the comment:
Attached is a new, simpler approach for supporting O!. The object() converter
now takes two arguments:
* type, which is the type you want the parameter declared as
(e.g. "PyUnicodeObject *")
* subclass_of, which is the PyTypeObject you want to enforce the
value is an instance of (e.g. "&PyUnicode_Type")
The old approach was kind of a lovely idea, but was too complicated, and it
would have meant registering any new type (like third-party types). This is
less convenient, but simple. And it would lend itself well to making a custom
converter if you used it a lot.
I'll write some documentation for it now, but I wanted to post the code so I
could get a review.
p.s. Why was is marked "crash" and "release blocker"? That's very inaccurate.
And assigned to docs? WTH?
