True.

Weelll, there's already a + operator, as in \df+. Perhaps there could
be a T operator for data types and an f operator for functions, &c.
\dfT integer
might bring back all the functions that operate on (or return)
integers.

Perhaps I didn't make clear what I was trying to say. :)
We should continue to avoid the "The docs for any given thing are
findable in exactly one way. If you don't divine it, you are S.O.L."
model of documentation.

There is nothing more difficult to take in hand, more perilous to
conduct, or more uncertain in its success, than to take the lead in
the introduction of a new order of things. Because the innovator has
for enemies all those who have done well under the old conditions, and
lukewarm defenders in those who may do well under the new. Niccolo
Machiavelli The Prince, 1513
