Just wanting to make sure… there are a handful of functions in the Task module that support different arities, e.g. Task.start/1 vs. Task.start/3, or Task.async_stream/3 vs. Task.async_stream/5. In all cases, the difference boils down to either passing an anonymous function (defined with fn) or using the long-form MFA notation.

From reading a bit about Task — Elixir v1.20.2 and Agent — Elixir v1.20.2, I understand that sometimes you MUST use the more verbose MFA notation to properly designate a function that will execute. Is the MFA notation only required when we are dealing with distributed nodes? Are the shorter function signatures (e.g. Task.start/1) only a convenience, or are there any cases where you would want to require that all instances of the module + function were the same version?
