Hi Emanuele,

intellisense it is very simple;
after a pattern matching, it count only
( -> incr expCount ) -> decr expCount
and , -> parmsCount like parameters separator.

When expCount=1 it show parmsCount-1 parameter on tooltips

Then:

MESSAGEBOX( (aMsg[1,2] ),
or
MESSAGEBOX( aMsg(1,2) ,

do not have the problem.
