Re: [OctDev] New functions and a question

[<pki...@co...>]

It doesn't matter what field you use.  Off hand I would suggest 
overriding Octave's 'class' function so that if it is given a struct 
as the first argument, it checks for a secret field name 
(e.g., __class) and prints that, or prints 'struct' if no secret
field exists.  If given two arguments, then set s.__class to
the second argument, which should be the class name.  That
will make the interface similar, even if the underlying
implementation does not yet support automatic dispatching
into the @class directory.  You could implement that too
if you were so inclined using find_in_loadpath([class,'.m']) to
find the directory, then creating a dispatch off struct for every
m-file and oct-file in that directory.

Octave supports structure arrays, at laeast in recent versions.
What syntax are you using to index and assign them?
