Yeah, i'm at least interested. If it works well and we have some good
tests for it (and, of course, all existing tests pass), i would even
support putting it into Velocity 1.6 (rather than wait for 1.7).
We've already got a lot of macro improvements in, this would Though,
i'd want the support of at least one other committer before doing
that. I do have one question and one suggestion at this point: Would
it work to overload the #macro directive instead of using #blockmacro?
(Not that big a deal to me, but people will ask.) And i would
suggest using $bodyContent as the default, instead of $yield since
that is more familiar to people.
This is a great idea though! People have talked about it, but no one
has ever taken it upon themselves to work on it.
