I think at least part of the justification is that it keeps the grammar 
simple. The tokenising happens identically irrespective of any modifiers. 
The r modifier doesn't actually change the syntax of the string at all, 
just the interpretation of the token.

If you changed this then the grammar would become slightly more complex.
