It's too bad that ints don't have a NaN value, but interestingly enough,

The compiler could always have flags specifying if variables were used, and if
they are false they are as good as NaN. Only downside is a performance hit
unless you Mark it as a release binary. It really comes down to if it's worth
implementing or considered a big change (unless it's a flag you have to
specially turn on)
Not so easy. Suppose you pass a pointer to the variable to another function.
Does that function set it?
