Hi
On elixir 1.3.2 when I run task mix dialyzer ( use
https://github.com/jeremyjh/dialyxir package ) , it generates many warnings like
```
The variable _@1 can never match since previous clauses completely covered the type #{'__struct__':='Elixir.MyStruct', _=>_}
```
in case of using code like this
```
%MyStruct{data | foo: bar}
```
On OTP17 and OTP18 this package worked correctly. But after update to OTP19 dialyzer gives many warnings like this.. How I can fix it?
