That's a great source 😄 Other than that, here's the PR where this was introduced and the related issue :) |

Zero arity functions should be invoked using parentheses to distinguish them from variables. The benefits are great, as a function call is a way more complex part of a program than using a variable so I believe it's important that those calls can not be mistaken for simple variables.
In a future version of Elixir not doing this will produce a compiler warning, so I think it's oblivious that this is also the opinion of the core team.
