Do we have to type parentheses now?  That more than undoes that gain :-/

There are users.  There are users who have been used to this behaviour
for many many many years.

People just do (say I have an "rtx insn"):
  p insn
  pr

A new version where you just say
  pr insn
would be nice; something that requires
  pr(insn)
is less nice.

It would be great if you could come up with something that keeps the
old syntax working as well, especially since many of us have to work
with older versions of the gdbinit as well, for years to come.  People
can adjust their work habits of course, but that causes a lot of
friction ;-)
