BTW I see you've written a blog post in response to my comment, and left the comments there off.

Guess you're not really serious about having this discussion, are you?

Oh, and please please learn how to write functions properly, before you submit another notation for analysis. That "w.i.p" was a complete and utter mess. This is basic algebra which you should learn before inventing notations of your own.

Either open a middle-school textbook that teaches the topic of functions, or ask the people here how its done.
