a lastcall-fn is a fn which returns a promise of its result, and tracks invocations such that if the results of multiple invocations are unresolved at any point in time, only the last invocation will return a result - all the others will error with [:cancelled {:fn <fn-name> :params <params>}]

provides a no-args version of the fn which will cancel any outstanding unresolved promises (where cancel means they will return [:cancelled ...] errors, nothing more - they will not be interrupted)
