I've pushed this patch. I didn't go with the macros in the end. I
just felt it wasn't an improvement and none of the existing code which
does the same thing bothers with a macro. I got the idea you were not
particularly for the macro given that you used the word "Perhaps".

Anyway, thank you for having a look at this.
