[metapost] aligning boxes

How can I control the spacing and alignment of a series of boxes?
I would like all boxes to be the same width, with padding if
necessary. Here's my attempt:
boxjoin(ypart a.s = ypart b.n + .5u;
xpart a.e=xpart b.e; xpart a.w=xpart b.w);
boxit.a(btex medium length etex);
boxit.b(btex short etex);
boxit.c(btex a very long string indeed etex);
What seems to happen is that box "a" gets drawn at its natural width,
and then the other boxes match that width. The result is that box "b"
has padding, and box "c" is too narrow: the long text spills out over
If I change the order, saying drawboxed(c,a,b), then I get the result
that I want. But I of course don't want to have to adjust the
drawboxed command arguments each time the text content changes.
Is there anyway to do this?
Hmm, do I have to do something like write code to find the maximum,
then draw that one first, and then draw the others? I thought the
"meta" way was to be able to declare linear equations in any order.
