Note having looked at your view adaptor class (, but quickly
over the VTL (of which I was unaware), I realize that I've developed
concepts here at work for, atop of what can be done with Blitz++ (from Todd
Veldhuzien). I'd certainly be all for such a library as part of Boost -
but geez,
the thought put into the VTL is both admirable, and induces one to
salivate (much
as Homer Simpson might do over donuts) ;-)
