Perhaps it is easier to approach it from the viewpoint of a new
user who is unfamiliar with what you designed.

I would imagine that most users would find it natural if a single
pass precedure read and processed lines as it sees them.

That is, when the first includeif is evaluated, we have seen only
'remote.a.url' whose value is 'bar', so the condition does not hold.
and then when the second includeif is evaluated, it gets included,
and we read 'bar'.  But that is wher configuration reading ends;
remote.b.url is not asked for after we process the second includeif
til the end.

If you explain

 (1) why such a simplest design would not work well; and

 (2) how the actual design is different from that simplest design to
     overcome it.

it would be easier to grok?

Thanks.
