Hello,

Let
function s = myfun()
    clear s
    s.a = %pi
    s.b = %z
endfunction

Presently, we get

--> myfun.a
Attempt to reference field of non-structure array.

--> myfun().a
  ans  =
    3.1415927

The type of the symbol myfun as a function is known when calling 
myfun.a, isn't it?

So, is there a technical or a usage reason to not understand implicitly 
myfun.a as myfun().a ?
As well, couldn't we expect an error message routing the user to 
defining %function_e()
(unless Scilab provides a default definition) ?

Thanks
Samuel
