Have you discovered other use case for amb related to async ? The retry is quite elegant.

it is a gold mine, especially in combination with loop to keep track of state. e.g when you need to emit a value and continue with state that depends on that value, (amb> value (recur value)) is very efficient (cf how-to iterative queries for a similar pattern). It is also a good fit to implement clocks
