Hello, I want to compute, for example d = a + b + c where a..d are of some derived type, without incurring the cost of temporaries for each overloaded operation.
In a similar post a while ago, Walter Bright proposed using function literals instead of template expressions to do this. After looking at function literals, I can't work out what he had in mind with this suggestion. May someone present a succinct complete example to demonstrate how solve this? Many thanks, Dominic Jones
