>From communication with Chuck Allison:
Bearophile mentioned that .reverse was deprecated. The problem with that is
that std.algorithm.reverse doesn’t return anything, breaking code like:
auto compose_n(Fun)(Fun[] funs) pure {
alias T = ReturnType!Fun;
return (T x) => reduce!((sofar,f) => f(sofar))(x,funs.dup.reverse); // <==
uses .reverse
}
I now about std.functional.compose, but that’s not the point. For functional
programming, we need values returned for cases like this.
Thoughts?
