### What it does
Checks for tuple structs initialized with field syntax.
It will however not lint if a base initializer is present.
The lint will also ignore code in macros.
### Why is this bad?
This may be confusing to the uninitiated and adds no
benefit as opposed to tuple initializers
### Example
```
struct TupleStruct(u8, u16);
let _ = TupleStruct {
0: 1,
1: 23,
};
// should be written as
let base = TupleStruct(1, 23);
// This is OK however
let _ = TupleStruct { 0: 42, ..base };
```
