Details:
When attempting to marshall a call to feval(), it is often the case that the
length of the argument list being presented is not known until run time.
Currently, the only way I can see of addressing this is to switch with a case
for each plausible number of arguments, but that is clearly very
unsatisfactory.
An enhancement would be to either
a) have a variable-arguments version called perhaps va_feval() or vfeval() or
similar, which would take two arguments - a function handle, and a cell array
containing the arbitrary length argument list to be passed to the called
function.
b) have a special case for feval(), where if it was passed exactly two
arguments and the second argument was a cell array, that it was assumed that
the cell array should be treated as the argument list for the function
called.
The latter is tempting (in terms of avoiding duplicating code within the
octave interpreter), but is not backwards compatible, and breaks compatibility
with matlab.
Implementation in either case is fairly straightforward (I'd be happy to do
the necessary).
