The perl regexp engine uses a substring optimization, where it examines the regexp to identify if there is a substring that *must* occur. Only if it occurs does it proceed to do a slow regexp search. Combining rules like this reduces fixed regexp overhead, but may make that optimization slower. You'd have to benchmark it.
