cell-array returned by anonymous function must be stored in variable before it can be indexed

[Olaf Till]

Octave version: 3.0 (on Debian stable, from a package in unstable)

If an anonymous function returns a cell-array, it can not be indexed
directly:

octave3.0:18> a = @ (x) {x}
a =

@(x) {x}

octave3.0:19> a (1){1}
error: scalar cannot be indexed with {

but only indirectly:

octave3.0:19> t = a (1)   
t =

{
  [1,1] =  1
}

octave3.0:20> t{1}
ans =  1
octave3.0:21> 

Such issues (having to store in a temporary variable before indexing)
are typical in Matlab, I saw it as an advantage of Octave that direct
indexing is possible. Maybe it is possible to provide that feature
(direct indexing) under all circumstances ...
