Hello,

I have a problem with the attribute "Listable".

It is said in documentation that a function is threaded over lists if
one of its attributes is "Listable". 

Neither the function N nor the function ComplexExpand has "Listable"
among its attributes and however both of them are mapped on lists of
numbers.

Can someone explain me ?


Thanks in advance,

J.M. CORNIL
