[Question][Hw1] module function 'int_of_bool' of 'Value' module not being declared on its signature

Hello, this might be unimportant but I discovered while solving HW1 that the 'int_of_bool' function defined on 'Value' module is absent on its signature.
I wonder if it is a minor mistake made during source code write-up, so it is up to student to add that in the signature,
or if it is intended and thus not allowed to add it.

Hi, we do not require you to add the signature of int_of_bool. Feel free to either ignore it or add the signature yourself.
