Yea, that's it, I sometimes reach for more generality than practice needs.
Sorry for confusion and thank you for your patience.
I hope that HAL/MLT designers shall be happy, but even if someone convinces us
that life without them is impossible (which is unlikely) it would be possible
re-introduce them without breaking backward compatibility since for plain (non
macro) names they have no effect.

Now I agree with you to omit START/END macros.
