Make the imported module callable about stack-overflow-import HOT 2 OPEN

Additional heuristic: in code blocks which contain viable executable code theoretically applicable to the problem, bare / outside the scope of a declared function, isolate the initial literal assignment(s) (which is/are most typically the sample input value(s) in short code demonstrations), remove it/them, and use the labels as the argument names of the generated callable. (Any trailing print call may be suitable for transformation into the final return.)

E.g. this following bare snippet in answer to "how do you multiply two numbers together":

x = 27
y = 42
print(x * y)

Would transform to, if imported as "multiply":

def multiply(x, y):
    return x * y

from stack-overflow-import.

Maybe it could look for an answer which contains a def block; if there are multiple def blocks, find the one that isn't called from the others.
