An experimental, generic, context-aware range for Go.
Sometimes, you want to range over channels returned by functions and semantically
out := make(chan out)
Range(ctx, in, out)
for v := range out {
}is semantically much clearer than for { select { ... } } . Plus, it's cleaner if
you have nesting out of the box.
Probably not. It's not type-safe because... Go. This also isn't something I'd actually generate code for. I really just wanted an excuse to play with reflection. That said, it would be awesome if this was magically a part of Go. The context package is very powerful but feels like a 2nd-class citizen (at least, for now).
