Thanks for the link, Pascal.

IMHO, that would be a better way to make TCO available, that is: TCO
should be explicit, since you know beforehand whether you want your
function to be tail recursive or not. Then, whenever you fail to
implement a tail recursion among mutually recursive functions, the
compiler should complain. If I'm not mistaken, OCaml has (somewhat)
explicit TCO. Or detecting such errors would better be left to test
cases?
