This is not done by the parser but by the scanner. In theory, it should
be faster, however, I doubt that a time difference is measurable in real
world code, the rest of the compiler needs much more time.

In 1.0.x the scanner took a significant amount of time due to the much
faster backend. I don't think it will matter with 2.x
