I'm interested in adding this feature; it was on my short list of things
that would be good to get in the next release.

The trick is that (a) the syntax needs to be chosen; I'm not so thrilled
about [], but that's something that can be changed pretty easily once
the implementation is available, (b) we need a good set of regression
tests for this feature, and (c) making it understandable in the
documentation will require some effort.

I'm not necessarily suggesting all these things must be completed before
the feature can be considered, but the more of them that are done or at
least attempted up-front, the less work I need to do to integrate the
new feature...
