Why must sentinel be known at compile time? I don't see what's in the

Performance!
It should be usable as a case in a switch statement.
Isn't it possible for the optimizer to inline the function call and then combine
the next ifs?
if (isSentinel(value)) {
} else {
switch(value) {
case ...
}
}
1. I don't know of any C compiler that would do that.
2. There are other cases, as I pointed out to deadalnix.
3. You still can't do lookahead without extra checks
Once again, guys, have a look at lexer.c at the lines I pointed out.
