Hi Michael,

OK, I tried looking into the code...

Are you speaking figuratively here?  I couldn't find it in the boost
sandbox.  I found a version in the vault, .1.1, dated 06.07.2006.  Is
this the latest?

I tried using the .h file as-is in msvc 8.0 but got a bunch of compile
errors on the test code provided in your e-mail.  Maybe it doesn't
make sense to do that, sorry I'm not too familiar with configure/make.
 I downsized the test code to where it did something pretty simple
(declared a cvalarray using the default consructor and printed its
values).  Anything beyond that and errors come up.

I am really interested, and would definitelly use this class if it was
made available in a boost-friendly way.  Actually, I've been looking
for something like this for quite a while :-)  Your class seems to
provide a pretty complete set of features (if I could get past the
compile errors :-)), at least as far as what I'm interested is
concerned.

The only thing I would see as a convenient addition would be
constructors and setter functions of the form

cvalarray<float,4> v1(1, 2, 3, 4);  // v1 = {1, 2, 3, 4}
v1.set(4, 3, 2, 1);  // v1 = {4, 3, 2, 1}

defined for sufficiently small array sizes (say smaller than UNROLL_LIMIT).

But even without that, I think it's very useful!
