This is how I inject the functions I am stubbing/spying/faking into the SUT. Why maps?
Because I like the syntax of my_map.deps.http.get.('blabla') rather than my_keyword[:deps][:http][:get].('blabal').
I have used keyword lists extensively by now, and I don’t really see the added value when compared to maps (you can also pattern match with them). Even if pattern matching with maps is more limited, I still prefer their less verbose usage any time of the day.
And no, I was not influenced by JavaScript 
Quite a brutal idea, but I still go for the first rule of macros: Don’t use macros.
I am not alone in my team, so I am not convinced by the price I would have to pay just because it would be fun. I would have to convince others, teach them and then maintain this position of mine. A price I am not going to pay alone without being convinced this truly has a gigantic benefit.
