We have great support for input ranges and thus for the pull-based model of
programming, but the standard library offers almost nothing for the
push-based model :( It utterly lacks tools for composing output ranges.
What I'd like to see working is this:
import std.stdio, std.algorithm, std.range;
void main() {
auto printer = fork!(n => n % 2)(sink!(n => writeln("odd: ", n)),
sink!(n => writeln("even:
", n)))
.filter!(n => n != 16)
.map!(n => n * n);
copy(iota(10), printer);
}
