> 2.2 Expression Calculation is a mixture of observations, rules and possible suggestions.
> For example, it starts by saying formulas are recalculated from "outside in," only to confess a few paragraphs later that is how it "appears to the end user."
> There is one really glaring hole in my proposal, that also exists in the current language.
> We describe the ordering of operators but as far as I can tell, we don't address the situation where there is a mixture of operators and functions.
> Note that I changed #1 from constant number/string and added error.
> As near as I can determine, the only possible outcomes of any expression are:
> 1) a number
> 2) a string
> 3) an error
> 4) a reference
> So, application of these rules self-terminates when any of those conditions obtain.
> Yes, that removes "constant number," "constant string" but those are defined elsewhere anyway.
