I was using the follwing form to see how many elements of list 1 occur in list2${reduce{ a:p:p:l:e }{0}{${if inlisti{$item}{ p:e:z }{${eval:$value+1}}{$value}}}} but this has stopped working in 4.96
To be fair, it wouldn't have worked with anything else rather than inlisti which left a result in $value. But... it's unfriendly, and therefore a bug. We could code to ensure that the $value used for the update operation of the reduce was always the one before the condition was evaluated - but then one couldn't ever use that nested result $value. We could code to stack $value during each evaluation of the condition for the reduce. That feels better. I'll have a go. [ There's actually a worse bug floating around here. I managed to trip an internal check on memory use, trying to invent an alternate using filter & listcount. ] -- Cheers, Jeremy -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
