When updating to elixir 1.10.2 I started to get a compilation warning because a
@spec annotation had been added to a function and was referencing a type that hadn’t been defined (same as this issue https://github.com/elixir-lang/elixir/issues/9758).
I use dialyzer to do static analysis but I’m now curious, what checks does the elixir compiler apply to
@spec annotations? (I’d previously assumed pretty much nothing aside from behaviours)
