Impossibly complicated to implement in the current situation, I think,
and also one doesn't always want to use macros. Macro expansion happens
when the string is read in, incidentally, so the fact that things were
macros gets lost at an early state.

Thanks. What I have implemented is \N...\N to mean "don't expand the
...". So you can write
hold_domains = \N^\d+.*\.com$\N : other items ...
