Context to contain to-ref function #17
Description
We're often faced with the unknown of wether a ref is a ref or whether we need to convert it. We've been using helper functions convert whatever is ref-convertible before calling pull. To avoid converting to refs over and over again it would be worthwhile to be able to pass a to-ref function to pull's context (today db-get-ref could be used as a hack).
