This is a very hard thing to do.  I suggest poking around 
'me:my_match_object'

Where did you even hear that you could?  They're called 'verbs'.

Nononono, I mean, CODE as in the stuff you put in when you type '@program...'

<verb>[[ <dobj>][ <prep>[ <iobj>]]]
Nowhere in this expression does it mention any builtin functions.  They 
may only be called from within CODE, not commands.  I think you're 
getting confused with unix shells.

There is, though, a verb that is called every time the server wants to 
match an object; <player>:my_match_object(<objname>);
The verb normally calls :match and then $string_utils:match_object.

With the following code, you can type the names of objects you own, even 
if you aren't near the objects.
You should write something like this:

me:my_match_object()
x=pass(@args);
if(!valid(x))
  what=args[1];
  for y in (this.owned_objects)
    (seconds_left<2 || ticks_left() < 50) && suspend(0);
    if(index(y.name,what)==1)
      return y;
    endif
  endfor
endif
return x;
