Functions without outputs that should have outputs still compile

[harrison8989]

Functions, despite being declared to return an output, do not actually need to return an output for the program to compile.
As an example, the following code compiles without issue, even though b should return a Number:

ReturnExample
Endpoint A;
A
{
    Public Function b() returns Number {

    }
}

More specifically, it looks like the compiler is not requiring the use of the 'return' keyword at all in a function definition which has a return type.
