no_unnamed_catch_all_pattern

[paulo-ferraz-oliveira]

Discourage stuff like

case ... of
  ...
  _ ->
end.

Encourage stuff like

case ... of
  ...
  _ConnectionResult ->
end.

Priority: low

A variant of this is no_unnamed_variables, to be applied to, at least, function clauses. Again, not a super-relevant thing, but an idea...

[elbrujohalcon]

I don't really like this rule.

Even when, in general, I write stuff like…

case MyVariable of
    …
    MyVariable -> …

…I still prefer using _ over _SomeName.

I don't mind this becoming a new rule, but not for the default ruleset, please 🙏🏻 .

[paulo-ferraz-oliveira]

I wasn't thinking for the default set, but maybe the strict. The rule is just a helper so you don't have to write your own; some people prefer all variables to be named, but yes, there are many cases where I just write _ as in "I want to ignore this wholly", and that's also valid.

Let's postpone it until somebody brings it up, maybe (?)
