Right, with that assumption, it's not that hard. And it becomes a test-only assumption, which is great!

But, I'm still not convinced this would be a good fix. The current struct documentation is consistent with *casting* char to _Bool, rather than doing the memcpy and reinterpreting as _Bool. The memcpy makes sense for larget types, but not so much for _Bool.

(Certainly, the docs' assertion that "the conversion between C and Python values should be obvious given their types" is not true here...)
