If we separated the namespace with something that involved a bit less
typing, would you use it? Say
\-dist users city
(Or some other char instead of hyphen)
The point is that you don't mix it with other \ commands, and as soon as
you put \- you can already press TAB to get a list of "aliases". So it
_is_ useful both for interactive use and script use.
"\query dist" is good for scripts but bad for interactive: too much
extra typing. Whereas "\dist" is only relatively good for interactive
(no good support for tab completion), and not any better for scripting.
