The most common way to do this in Clojure is to define your function such
that if the input is not in the domain, the function returns nil.
Since nil and false are the only "falsey" values in Clojure, you can use
ordinary tests to determine if the function returned a result. The idiom

The list of maps is retained which might be useful later.

Seems to me that (merge {:attr something} obj) answers the OP's question,
mentions obj only once, and is short and pithy. OTOH it computes the

"something" is expensive to compute (or has side effects that should only
