No I simply  havent tried it out with pqs. I apologise as I said that I 
would try it in pqs out some months ago. I will try to spend some time on it 
and get back to you.
However there are various aspects to type deduction and I dont expect 
BOOST_TYPEOF to cover all of them. I think it is more of a user  mechanism. 
rather than an implementation mechanism. ( Well for me as macros cause me 
error finding problems... maybe this is a user issue too.)  pqs requires a 
fair amount of template machinery in the implementation ( and I think some 
might be needed in pqs even with mods to the language).
