The current dictionary syntax is actually typical for lisps, particularly this is exactly what Clojure does. It's just a series of elements except in this case it's designed to look at every two elements as a pair. What do you mean by it's inconsistent? Commas are the same both in dictionaries and anywhere else, they're completely optional.
