Does this:

int isfuturediv(void) { PyCompilerFlags cf; PyEvalMergeCompilerFlags(&cf); return cf.cfflags & COFUTUREDIVISION; } work?

Yes! That's exactly the sort of thing I was looking for. I couldn't find the "PyEval_MergeCompilerFlags()" call.

You'll need to change this when future division becomes the default, but I think it'll work today. This is a murky dark corner of the interpreter, though -- so don't blame me when it breaks!

I knew this, but my alternative was having to change behavior when future division becomes default, which would be much worse.

When I decided to try to make my module into a patch and bend integers and longs to my will I knew that I was going to have to enter murky corners of the interpreter :-)
