Could you please elaborate on why you believe it is safe to move the check of
`Current.Previous` inside the body of the `if` statement? Doing so will short
circuit the remaining `else if` cases such that `Current.setType()` will not be
called at all. It isn't obvious to me that those cases should not be considered
if the previous token was not one of `kw_operator` or `identifier`. This looks
like it has potential to change behavior.
The change that was originally proposed is clearly safe.
