Yes, but for that is the compiler-switch $PASS_VAR_NO_HINT ON. Then no hint is put out by the compiler. If this switch is on the programmer is resposible for initialising variables which pass a function. If someone doesn't find it useful then he/she is not forced to use the switch. I would use this switch if it exists. My code is full of this passing variables through procedures/functions. And also I wonder of this many hints.
