I think speed of interpreted code is important for most users of
Octave. I was merely expressing my opinion that Octave's oct-files are
easier to use than mex (despite the lack of docs), and thus if you are
forced to meddle with compiled code, it will be less painful. The C++
code can be very similar to m-code decorated with type declarations.
