Subject: infix operator "<>"


Under Semantics we say:

> Returns NOT(Left = Right) if Left and Right are not Error. Note that 
> for Text values, if the calculation setting |table:case-sensitive| is 
> |false|, text is compared but characters differencing only in case are 
> considered equal.
But that's not right. Returns a logical, true/false. Yes?

We further say:

> Note that if either Left and Right are an error, the result is an 
> error; this operator cannot be used to determine if two errors are the 
> same kind of error.
> Note that in some user interfaces, this is displayed (or accepted) as 
> “!=” or “≠”.
OK, let's not repeat the error comparison mantra, which should be 
defined elsewhere as well as the text comparison text.

I am assuming that the final paragraph is a true non-normative note and 
am marking it as such. "In some user interfaces the infix operator "<>" 
may be displayed as "!=" or “≠”.

Raises the issue of what role does the "semantics" section play? Does it 
simply repeat what as already been said under summary? Or is it a place 
for general observations that should more properly be notes?

BTW, should I be creating JIRA issues for these comments?

Hope everyone is having a great day!
