If your goal is to reduce the scope of variables then yes,
withwill work okay for it. Personally I’m not sure I see the value though. Any specific goal or use case that you have in mind?
Basically the same as let in Clojure, to assign a variable that can only be used within the scope. It may sound rudimentary for people used to Elixir, but they greatly reduces mistakes due to scope pollution in my opinion.
What does “let” do if the map does not have that key?
No error handling as is the case with with.
Overloading
with(not Elixir’s most obvious construct) with additional semantics seems like a maintenance issue waiting to happen.
No overloading is needed, this already works.
