There's nothing for me to learn here other than domain theory which is very advanced math and how people behave. If you follow the conversation you'll see that the entire argument turned into a battle of definitions with me turning to a very generally accepted definition of a function and bitdizzy turning to using more obscure mathematical definitions of "function" and arguments about semantics what context is relevant to what definition of "function." Whatever definition you choose to believe domain theory looks like very advanced stuff and clearly outside the scope of your average technical conversation. Either way, I didn't have time to respond to your other comment below. But I will now. Don't worry about the upvote thing. It's just for this thread I can switch accounts.
