Review Comment:
Can we maybe rename this method to `parse_dictionary` and
`parse_dictionary_field` respectively? so that the name doesn't change as a
result of dialects being extended to support it

Review Comment:
I think here it would be fine to parse an arbitrary expression instead, in
order to simplify the logic, and likely to have comprehensive support covering
other scenarios
```rust
let value = self.parse_expr()
```
