Do you mean "responds to arithmetic messages" or "could be converted
into something that responds to arithmetic messages"? #isNumber means
the first (to me); your use seems to be the second. Given that I have
code that tests for #isNumber before sending (eg) #+ to an object, I'd
be unhappy about the second use!
