Details:

Contrary to what declared in the docs, the last three commands give different
results, while they should be equivalent:

> clear a
> a.first.fd = 1;
> a.second.fd = 2;

> for [val key] = a; disp(val.fd); endfor
       1
       2

> for [val] = a; disp(val.fd); endfor
error: structure has no member 'fd'
error: evaluating argument list element number 1

> for val = a; disp(val.fd); endfor
error: structure has no member 'fd'
error: evaluating argument list element number 1
