Follow-up Comment #17:

@jwe: I tested this and it works fine


octave:1> x = {1, 2; 3, 4}
x =
{
  [1,1] =  1
  [2,1] =  3
  [1,2] =  2
  [2,2] =  4
}

octave:2> x()
ans =
{
  [1,1] =  1
  [2,1] =  3
  [1,2] =  2
  [2,2] =  4
}

octave:3> x{}
error: invalid empty index expression


One final idea.  Since empty indexing '()' of regular objects is likely to
indicate a coding problem, could we emit a warning when that is used?  It
could be a warning_with_id() so that the whole mechanism could be switched off
easily if a programmer has used the construct extensively.  Otherwise, it
would be a good note to the programmer to change the one or two instances of
their code that use this.
