Interesting.

As a general solution I'm not sure it's what I want.
I am also expanding complex objects (e.g #{posting.attribute}) and
with your custom interpolator I would end up either having to copy
information around (e.g. :posting_attribute => posting.attribute) or
using it with the regular delayed string interpolation strategy anyway.

Thanks,
