Follow-up Comment #6, bug #53198 (project octave):

Using the 80/20 rule, I think the biggest gains would be made by changing sort
and issorted.  I'm okay with leaving reshape and permute as they are.

There is some question whether this should be done in the interpreter library
or in liboctave but we could punt on that for now and just do it in the
interpreter.

Do you want to go ahead and convert the pseudocode to a patch?
