[Exim] Named variables

I'm sure this is a far-off wishlist item, but is there any interest at all for named variables instead of the acl_ variables? I know that the current code is very specific to that format, but 20 variables are really not enough for a very complex configuration and having named variables (even if they were local to the type of acl they were in) would definitely sweeten the maintenance and extension of a complex setup.
