[06:43:25] <McSinyx[m]> toad_polo, the number represents the version of A, sorry for not making it clearer
[06:47:18] <McSinyx[m]> IIRC for setuptools-backed sdists the resolver runs `setup.py egg_info` and that may success (since it doesn't compile the extension modules) even if `setup.py bdist_wheel` doesn't
[06:48:45] <McSinyx[m]> still, I was more curious about what is the intended behavior, i.e. should the new resolver skip a unbuildable candidate or everything is allow to crash and burn
[06:49:58] <McSinyx[m]> for the current behavior, `pip --use-feature=2020-resolver install brutalmaze` on Windows may show some inside (a dependency named palace can't be built on Windows out-of-box)
