Seems like an awful lot of extra script work (esp if there are many
contributing rules) to save a single shell operation at the end where
it gets evaluated.
If it really is only going to be evaluated once at the end, then you're
right. If the interim values are going to be used several times along the
way, then the extra scripting might be worthwhile to avoid forking shells.
As usual, it depends on what you're trying to optimize.
