Sometimes in worksheets the formulas can get out of hand, and when you open a
file a while after you last touched it, you can no longer understand some
formulas you have in your worksheets.

Can you please include syntax for cell function parser, so that it is
possible to add any comment text after the last bracket and it'd just ignore
it. You can even have an apostrophe like in VB to avoid inveting a wheel.

Say, such a formula including comment could be valid in a cell:
=(EOMONTH(TODAY(),0)-EOMONTH(TODAY(),-1)) 'counts number of days in a
current month.
