We need to allow writing generic functions (templates) and template constraints.
One idea that we can explore is to also support something like: #152 (comment):
>>>defstr(val: i32|f64):
... # "isinstance" type guard
... ifisinstance(val, i32):
... # type of `val` is narrowed to `i32`
... returnstr_int(val)
... elifisinstance(val, f64):
... # else, type of `val` is narrowed to `f64`
... returnstr_float(val)
