I feel you! I worked with Hashes in Perl since the 90s, Did almost 10 years of Java used Dictionaries in the early versions of C#, switched to JS, Ruby and Clojure for a while and didn‘t remember how to correctly declare a typed Hash in Java in a programming kata - ouch! So if you are a unicorn, you need to find a special environment i guess?
