[Scilab-Dev] &&, ||, {} as cell-builder not overloadable: official?

[Samuel Gougeon]

Hello,

Could we have the confirmation that the new Scilab 6 operators &&, ||, 
and {} heterogeneous concatenator are not currently overloadable?
Is this their official stable status (=> creating some first official 
exceptions), or should it be considered as bugs to be reported?

Thanks
Samuel
