Right, I was confounding with C ;)

In fact, respect to this question, the documentation makes things 
unambiguous :


-----------------
In contrast to many other languages, not all language constructs are 
expressions. There are also statements which cannot be used as 
expressions, such as print or if. Assignments are also statements, not 
expressions.

You are probably right but how do you deduce this brilliant 
interpretation from the wording given in the documentation ?
