// This is a test where I was trying to isolate how much we lost to `reflect`
// with channel operations in a tight loop.
//
// PREAMBLE
// We do a lot of processing of stream data where ordering with respect to a
// shard indicator like user ID matters. We've done this a few times where we
// implement fanout based on hashing into an slice/array of channels, and it's
// lightning fast but it ends up leaving a lot of boilerplate in your code.
//
// So I started writing a library that would do the non-critical boilerplate
