----------------
I'd prefer if we somehow find a different solution than having traversal implemented in more matchers.

I think that with the upcoming backwards references, this can be expressed as:
switchStmt(
  stmt().bind("x"),
  forEachDescendant(
    caseStmt(hasAcenstor(switchStmt(equalsBoundNode("x"))))
  )
)
And while I'm not completely happy with the matcher, I think that'll buy us time to come up with a better design for doing matchers like this (basically getting early exit for forEachDescendant style matchers).
