I accept that my original sentence was unclear. I mentioned more punctuation characters in the context of conciseness, which obviously takes the amount of characters into account. Other than that, I don’t dispute Erlang has less syntax and I hope it is clear that Erlang is noisier (assuming the definition of noise is punctuation / character).
Regarding the compiler, most compilers have ambiguity. It is the reason why you have to put a space between = and binaries in Erlang. The question is if the compiler is going to pick a side or require the developer to be explicit. Modern compilers prefer to fail early in such cases, rather than letting a syntax error pop up later on.
Furthermore, the use of do/end vs do: is completely up to you. My original draft had only the first, which reduced the amount of punctuation in Elixir further, but I decided to include both styles because you will find both in practice. But if you want to stay consistent, you have the option.
Finally, happy to disagree on the “agglomeration of characters” in the Elixir example. The Elixir code has less punctuation and is clearer, despite the use of “do:” (which, as I said above, is optional).
