Thanks for the fix, it works for my use case. (btw that was
#define U(...) __VA_ARGS__
and not what I wrote).

For Python 3.8 that fix wouldn’t be needed as the `tp` argument was
parenthesised in the macro.
Yet... the first argument is still unshielded, passed to a macro that expects
one single macro argument. That’s not a regression, it wasn’t shielded in 3.8
either, but why not just parenthesise each macro argument that denotes an
expression (as opposed to e.g. name)?
