Fantastic. There is one niggling thing that worries me about this
solution though, but it doesn't apply in my circumstance:

>> warn set acl_m4 = $acl_m4\n$local_part@$domain=YOUR_UNIQUE_ID

What if $local_part contains an '=' ? I guess it needs escaping
somehow...

This problem wouldn't exist if there were some inbuilt functions for
working with hash style acl variables, other than extracting from
them. Eg:

1.) ${hash_add{$acl_m4}{key}{value}}
2.) ${hash_get($acl_m4}{key}}
3.) ${hash_rem{$acl_m4}{key}}
4.) ${hash_exists{$acl_m4}{key}}

1.) Changes the value of acl_m4 and also returns the new acl_m4
2.) Returns the value of key in acl_m4
3.) Removes the value of key from acl_m4 and returns the new acl_m4
4.) Checks for the existance of key in acl_m4 and returns a boolean

Or similar.
