Problem description: So this is not so much a problem. More of a question.

As you can see below I'm wondering when return would be required. I know when else comes into to play I don't think that return is needed.


Code:
mob/proc/test()
    if(variable)
        //things
        return

    usr<<"No return"

mob/proc/test2()
    if(variable)
        //more things

    else
        //some more

mob/proc/test3()
    if(variable)
        //things
        return

    if(anothervariable)
        //things

    else
        //things

return is technically never required, as there are alternatives to using it.

For example, instead of this:
proc/thing()
    return "thing"
    world << "This line isn't reached!"

You could write this:
proc/thing()
    . = "thing"
    goto end
    world << "This line isn't reached!"
    end

Of course, the former would be most preferred.
