green(a + blue(b) + c) will now look the same as green(a) + blue(b) + green(c), as expected. In the previous implementation the output would have been green(a) + blue(b) + c, because the reset code of the second expression would close all expressions around it as well. Now this reset code is replaced by a start code of the outer lying expression, both stopping the inner and re-starting the outer.
