The problem is, that since a procedure can now have a return value, there is no way for the transpiler to tell what the intention of the programmer is.

Just suppose hypothetically, that it was "possible", and I had the following program:

Global HIT
HIT=3

Procedure HIT
  Print "hit"
End Proc[5]

Print HIT 

Here's where the conflict occurs. Is the result 3 or 5? There is NO way to tell.
In order to know the difference, the computer would have to read the mind of the programmer.

The only way I can see around this would be to REQUIRE an empty set of square brackets in the Procedure definition for a procedure without parameters, in order to differentiate it from the variable with the same name. I don't think we want to do that. I'd rather avoid the [] on procedures with no parameters, that to have the dubious option of having a variable and a Procedure with the same name.
