About
Guess the maximum number of arguments the given function will consume.
Determines, with a small amount of analysis, whether the function is variadic. Suspected variadic functions will produce Infinity.
Intended use case: sane defaults for optimization flags in developer-oriented tooling.
Please don't use this in your production code.
