Thank you for the information, Daniel. You are right: I didn't even know 
"delegate" is used in the second sense. Then, what is he difference 
between a delegate in the second sense and a (non-static) "member 
function" (I mean a method)?
Or is "delegate" the name of the data structure (implementation side) 
and "member function" or "method" the name of what it holds or means 
(semantic side)?
