7Parso doesn't attempt to parse (or even emit tokens for) whitespace or comments that 

8aren't syntatically important. Instead, we're just given the whitespace as a "prefix" of 

9the token. 

10 

11However, in our CST, whitespace is gathered into far more detailed objects than a simple 

12str. 

13 

14Fortunately this isn't hard for us to parse ourselves, so we just use our own 

15hand-rolled recursive descent parser.
