I could do CommaRange = findToken(tok:comma) an do a in-place replacment and thus, get rid of the workaround part as well. But for the TypeRange, I didn't find a proper way to get only the type part. For example, getTypeSourceInfo()->getTypeLoc().getSourceRange() for

  const int a(1), b(2);
  int const c(3), d(4);

will be

  const int
  int

I am not able to get the qualifier as well. I even saw something in the source like "we do not provide SourceRange for Qualifiers...". I would like to get rid of getUserWrittenType, but didn't find a way. It gets also dirty for MemberFunctionPointers:

  int S::*p = &S::a, S::* const q = &S::a;
  const int S::*r = &S::b, S::*t;
  int const CS :: * pp = &CS::a, CS::* const qq = &CS::a;

TypeRange will be

  int S
  int S
  int const CS
