[exim-dev] nested list operations

Messing around with Heiko's issue I started trying to
lay out some example coding, and ran into some brainfade.

I'd got to here:

${if forany \
     {mail:EximMailPrimaryAddress:EximMailAlternateAddress} \
     {inlisti {$local_part} \
              {<, ${extract {$item} \
                         {${lookup
ldapm{ldap://localhost/ou=users,dc=example,dc=com?mail,cn?sub?cn=user4}}}\
                }\
              }\
     }\
 }

and, replacing the $local_part for testing, failed like so:

> ${if forany \

     {mail:EximMailPrimaryAddress:EximMailAlternateAddress} \
     {inlisti {user4alternate2@???} \
              {<, ${extract {$item} \
                         {${lookup
ldapm{ldap://localhost/ou=users,dc=example,dc=com?mail,cn?sub?cn=user4}}}\
                }\
              }\
     }\
 }

   result: mail:EximMailPrimaryAddress:EximMailAlternateAddress

This looks to be a syntax-check initial run through
the arguments for the forany, failing because $item
is empty and ${extract requires nonempty.

Replace the $item with a dummy and it works.
Ideas?










(full expansion for the working test-hack:)
