As much as I love lisps, and I've written a fair bit of code in Scheme, Racket, and Clojure, I have to admit, when you are an immigrant in another person or organization's code, their specific abstractions, DSLs (macros), etc., can be very (VERY) burdensome to get up to speed on to even begin to start contributing to the codebase (much less debugging complicated issues).
On the other hand, there is a ridiculous amount of power in Lisps. Operating at a higher level of abstraction is like having magical powers. When you go back to programming in Go, you feel like someone chopped off one of your arms or legs.
On the other hand, to be fair to Go, when you are an immigrant in a Go codebase, everything is very easy. Turn this way ... oh I've seen this a thousand times before its an XYZ. Turn that way, oh, I don't even have to read that, I know what that is. Oh what is that ... oh its my greencard to this codebase, I can now fix bugs with confidence.
