If you're talking about this:
I would be tempted to rephrase "Erlang is not good for ..." with
"Erlang is not what I am used to for ..."
Some languages invest tremendous effort in programmer convenience and
fit and finish. I think this is terrific! It's one of the major
appeals of Elixir vis-a-vis Erlang and has inspired a huge influx of
creativity and contributions within that ecosystem.
However, when it comes to the merits of a language (and it's
libraries, runtime environments, etc.) there are trade offs
*everywhere* and some of these conveniences come at a high cost. I
don't think "good" and "bad" are nearly specific enough to help inform
our decisions about language adoption.
Now the following is *my very personal opinion* and I'm not grinding
any ax here, extremely happy to live and let live, but this: I don't
particularly find writing function(Arg) (as opposed to Arg.function)
hard, at all - and I *certainly* don't want to pay *any* price in
terms of added complexity or performance degradation for object
oriented ish semantics or features. That's me though. I know a lot of
people really like their language features and thank goodness we have
