FWIW: Matlab's containers.Map is a bummer, because it's a
pass-by-reference handle object, so it doesn't play well with normal
Matlab/Octave objects and data structures. I've found that this
limitation makes it basically useless for M-code programming over the
last couple years.

It would be nice if there were a pass-by-value/COW version of
containers.Map. I know that Octave core is shy of "innovating" in
non-Matlab-compatible ways, but maybe an exception should be made here.
