Basically yes; the discussion came up briefly during protocol oriented integers
where this is quite common, especially with added methods for handling
double-width operations and such as well.

Huh, that could be a great alternative! It would solve the ambiguity issues
completely and allow for even single argument cases (if someone wanted to use
those).
Any preferences on how to specify these arguments? e.g- just declare them void,
attribute or something else?
Also apologies to Patrick, I seem to be leading his discussion, I really should
get some work done! 😄
