functions that come to mind

• pipe f g & more: pipe the result of (f request) to g and so on until more is exhausted. Returns a function that will return a channel with the result of the data transformation.
• pipe! f g & more: same as pipe but returns an exception if any function returns one.
• chan?: is this a channel?
• inject: takes a query, a map and a key and returns a new map with the result of that query assoc'ed to the map
• <?: error handling for cljs async operations

note that pipe is like comp in that it describe a data transformation. There is a no concept of request/response as in ring middleware. Simply stated data comes from the left and exits through the right, whether sync or async.
