Then we'll have to explain to people that sum is a mathematical function,
although integrate is not. Plus we get to tell them that if they define
something like dawson(x) := <asymptotic series here>, that's not a
mathematical function.
I'm not looking forward to that.
Whether sum, integrate, or whatever are implemented by DEFUN,
DEFMSPEC, MDEFINE, MMACRO, or whatever is a secondary,
or maybe tertiary, consideration from the user's point of view.
