Subject: SI Units - has Ada missed the boat?

One of my pet hopes for Ada2005 was that it would include some method
of automatically checking systems of units at compilation time or with
minimal run-time checking. Alas it was voted down due to time
pressures and technical issues (see http://www.ada-auth.org/ai-files/minutes/min-0403.html#AI324
and http://www.ada-auth.org/cgi-bin/cvsweb.cgi/AIs/AI-00324.TXT?rev=1.3).
C++ now has the Boost library (see http://svn.boost.org/trac/boost/browser/sandbox/units)
with zero-runtime cost (or at least when optimisation is switched on).
And now Java has a proposal for a similar beast (see
https://jsr-275.dev.java.net/files/documents/4333/34956/jsr-275.pdf).
I've been playing around with the C++ Boost library and it seems quite
good - at least for the sort of things I would use it for (embedded
avionics).
Is anyone still working on an Ada solution to this?
Cheers
