I wasn't talking about the name, only about the fact that it's implemented 
as a function and not as a language construct (i.e., it can't tell the 
difference between existing variables who have the null value, and non 
existing variables).
It's too late to start putting _'s in language constructs, we already have 
isset() as a precedent :)
