==As for type...yeah, oops. We kind of forgot to include that. :-(
Nice thing is it only takes a short time to code it (probably an hour or so for something this simple) and it is fully integrated into the system. To define a system function/variable you provide: a name, getter/evaluator, setter (if a variable), min args, max args, algebraic priority, enabling of automatic input processing including list processing for specific agrumnts, whether it requires full qualification (C1 versus Statistics_2Var.C1 - eg. global or not), special printing if needed, Help, Menu id, and special printing for 2d mode (sigma or the like).
Then you have a new function that will work properly everywhere - including the help interface, placement in the appropriate menu location and even will handle special printing in 2d display mode!
Contrast that with adding a built in function to the 50g ROM. Might take anywhere from a week to much more depending on quite a few factors.

The best way - it is good to know mathematics and not to wait for implementation of promises of Prime "developers". The mathematical part is realized in Prime at the high level. Don't carp at trifles. If Prime holds on in the market of 5 years, then I too will buy it.
