The point is, if the lexer simply requires an input range, and not a sentinel input range, it is more flexible for its input. But when it does get called with a sentinel input range, the optimizer can reap the benefits.
I suggest you compile lexer.c with various compilers, add in a !empty() call before every front(), and verify your assumption about this.
