I second this feature, I need function chaining everyday, and I've myself
brought up the issue some days ago (you replied suggesting the use of lambda
library, but I'd still like to have a solution that doesn't use lambda, for
several reasons). Also, the syntactic sugar I've proposed (operator+) still
looks good to me.
