Operator precedence is different from what you think. `a ? b :
c = d` means `(a ? b : c) = d`. But you want `a ? b : (c = d)`.
So you need parentheses around `p+=1`.
Or just go with `if` and `else`. It's clearer anyway.

I was actually close to not needing parentheses :). But I see
that your suggestion to stick with if else in this case is the
sensible thing to do, especially since ?: seems to lead to more
errors. Thanks for the answers.
