[Erlang Forums] [Erlang/OTP Proposals/Proposals: RFC] Re-visiting EEP-0055
Mon Apr 25 14:00:16 CEST 2022
I agree with this point. Less is more.
So far, Erlang managed to keep most of its core features orthogonal.
Which helps adoption, since Erlang is a niche language with a
well-defined problem domain in mind: it makes implementation of
asynchronous and distributed systems easy and efficient. I'd had
experience mentoring fresh graduates and juniors in Erlang, most of them
were able to provide value to the product after three-four weeks of
No one is going to bother learning a complex feature-rich language for
just one domain. Currently Erlang is a nimble and efficient craftsman's
tool, not a Swiss knife. Keep complexity for "general-purpose" languages
that try to do everything, poorly.
