You lost me. I am still talking of the specific case of a format flag that knows we are sending stuff to a Gmp.mpq constructor, and not any constructor in general. I find it reasonable to pass on some knowledge of what that constructor handles to sscanf if implemented this way.

Why should it not read "kladdakaka"? If the program passed is for example Stdio.File, then "kladdkaka" might be a perfectly acceptable choice. I don't see why your examples should be more suited to pass to constructors in general (as opposed to your specific example) than other strings.
