Why is the distinction important to uphold (on the
level of the programmer)?

Even more so, as sometimes (when?) functions should
not be denoted functions but symbols - as the example
with `put' had it.

If I use `quote' in both cases, and it works, I don't
see that as a mistake in either case, actually I see
that as much *less* error-prone than each time
considering if the sharp quote should be used. It is
much better I let the computer sort that out.
