My OCD says: better typewise/error reporting is of course:

global type valididx(object idx)
   return integer(idx) and idx>= and idx<= length(defset)
end type
global function getstr(integer idx)
  return defset[idx]
end function
procedure useit(valididx idx)

 

Thataway any error should occur on the useit call itself, not two levels down in
the call stack...
