I don't know what type my function's return type will be until I have made all of the code up to the return statement. Most of the time this works, however, when I try to do recursion, I get errors due to mismatching types. In addition, these errors are panics, so I can't ignore them. Is there any way to ignore these types, and have it figure out the types when converting a module to a string (because, by then, the types will all be figured out)?
