Not all Exim users are experienced programmers and may not understand
why they would have to initialize a variable to zero before they can
do an otherwise simple task.
For example, the following (made-up) example will generate an error
with Exim 4.65 where it worked fine previously:
warn dnslists = sbl-xbl.spamhaus.org
set acl_m0 = 1
warn dnslists = dnsbl.njabl.org
set acl_m0 = 2
deny condition = ${if >{$acl_m0}{0}}
Keep in mind that it is *documented* that acl_m0 is reset at the beginning
of each message, so a reasonable person may assume that doing a numeric
comparison against it is always safe.
To make this work, I would have to add the following at the beginning, which
a new user to Exim may overlook as being unnecessary:
warn set acl_m0 = 0
