Structures 6.1.1 Basic Usage and Examples

[Andreas Weber]

The manual
http://www.gnu.org/software/octave/doc/interpreter/Basic-Usage-and-Examples.html#Basic-Usage-and-Examples
shows

x.a = 1;
x.b = [1, 2; 3, 4];
x.c = "string";
x.b.d = 3;
error: invalid assignment to cs-list outside multiple assignment

which works in Matlab and since it's in the manual I guess this also
worked in octave somewhen prior 3.6.2.

I'm not sure if this is related to
