This is hyperbolic. The author isn't some kind of bumbling fool who can't program, as you seem to be suggesting, he's an accomplished computer scientist. And foregoing the return instruction doesn't prevent you from writing "nontrivial" code, you only have to look at the entire Elixir ecosystem if you need a proof.

He doesn't seem to have had a job in industry though? Which seems a bit suspicious to me. On the other hand implementing Eiffel should be somewhat like having to write real code I imagine.

For other readers:

Elixir has a special syntax for what is early return, namely guard statements.
