I would ignore the GP's advice. Channels are prone to big errors -- panics and blocking -- which aren't detectable at compile time. They make sense to use internally but shouldn't be exposed in a public API. As one example, notice how the standard library's net/http package doesn't require you to use channels, but it uses them internally.
