What's not particularly nice though is to hide these in a macro,
which itself may be part of a larger macro or code fragment also
using small numbers.

We probably ought to be a bit more inteligent about how we choose
these numbers inside macros, rather than just randomly picking some
and hoping that they don't clash.
