Hmm, isnt that just boost::lambda? I haven't used boost::lambda much
yet, and i am not really proficient in functional programmign either,
but could not the example form the page above:
DExpr<DExprIdentity> x; // Placeholder
evaluate(x/(1.0+x), 0.0, 10.0);
be written in boost:lambda as follows ?
evaluate(_1/(1.0+_1), 0.0, 10.0);
If yes, what exactly can expression templates do that boost lambda cannot ?
