By passing a function as a parameter to another function, I mean

function exec a

function seven
    return 7

print exec(seven)

Here we pass the function seven to the function exec as its a parameter, and the ``exec``` function executes it, ultimately resulting in 7 being printed.

Is this behavior allowed in ml? If it is, how do we get around c's function type checking? I believe that to pass a function to a function, its necessary to create a function pointer like so void func ( void (*f)(int) );.

Also with respect to functions with the same name, should we assume it never happens or check it?

No ml doesn't allow passing a function to a function. It is too complex for this project, and I don't believe it will be covered in the unit.
