Re: namespace support?

One could almost write an M-file function called "import" to implement
this in Octave without modifying the interpreter.

It might work by creating function handles to functions that are not
on the path.  However, attempting to invoke a function handle that
points to an M-file that is no longer on the path results in the
following error message:

error: invalid function handle

Matlab does support function handles to functions that are no longer
on the path.  How hard would it be to implement this in Octave?
