the reason is that you are trying to access an undefined variable. y is only defined in the scope of the try-block. This is checked if you put these methods inside a class, but not in scripts.

the program will noe throw a MissingPropertyException since you defined a local variable y which is only visible inside the try block. The return uses a y, but this is from the binding. Removing the def means, the return will succeed.
