Yeah, the fundamental difference between the backslash command situation
and aliases in shells and suchlike is that, because we've historically
allowed no space between command name and argument, it's not that easy
to tell what string ought to be compared against alias names.
I think that an alias facility would only be acceptably safe if we
disallowed that syntax (ie, start to *require* a space between command
and args). Are we ready to do that?
This discussion really needs to be moved to someplace more widely read
than -patches, btw.
