Feedback from ODF 1.2 OpenFormula (=)

It's very strange that the '=' is not necessary required for a formula.

Everything actualy uses it as a requirement.

It allows me to distinguish between:

a) a value calculated by a formula
b) showing a formula in a cell in a spreadsheet as a string

Please make the '=' mandatory because everything requires it and it
makes something possible.
That would otherwise be impossible.



(A function to get the formula of a cell as a string in a cell,
?other? places would be nice.)
(That must return exactly what the user has typed in.)
