It's not so much that "'require' behaves in this way" as it is that
require exposes the common behavior more readily. You can see it with
any verb using something with side effects, e.g. set or logwrite. For
example, to look up the country of the client by their IP address and
default to '??' if the country is not known:

  warn set acl_c0 = ??
       dnslists = zz.countries.nerd.dk
       set acl_c0 = ${uc:$dnslist_text}


The seconds 'set' will only be executed if the dnslists condition
passes.
