Re: @ ( ARG_LIST ) STATEMENT syntax

[David Bateman]

Why not make anonymous function handles be created in the class
octave_fcn_inline. It would still have all of the features of a
function handle, but you'd also be able to run Fformula on it to
recover the formula used. At the moment there is no way to find
out this information once it is set.

Cheers
David
