I would love to do that.  Unfortunately, I'm not the one paying the 
bills :)  (I do, and will continue to, lobby my management to keep 
current and ensure we report defects and fixes).

The effort isn't always so small for us however.  It has generally taken 
us about a month to upgrade and vet a new Clang release.  The Clang 
release cadence is faster than ours, so timing isn't always great (not a 
complaint, just a reality).  Before we upgrade again, we also have to 
port our internal code and build systems to C++11 since Clang now 
requires that (again, not a complaint, I'm glad to see Clang using new 
language features!)

Yes, this is pretty much our strategy.  I've been very happy to see the 
dot releases being done.

I agree.

Tom.
