ah, sorry, I didn't check our impl - so then it should work, just isn't
portable

Indeed, according to the FDIS size() is *not* constexpr, but I had initially

obviously it shouldn't crash, but what you're trying won't work, because
initializer_list::size is not constexpr, so il.size() is not a constant
expression
