Anything generic over SelectDsl allows errors

[jethrogb]

Any trait bound involving SelectDsl will error out with error[E0275]: overflow evaluating the requirement [...]. At least, I have not been able to write anything where that's not the case.

For example:

extern crate diesel;

use diesel::SelectDsl;
use diesel::expression::count::CountStar;
use diesel::types::BigInt;
use diesel::query_builder::SelectStatement;

trait MyTrait {}

impl<T> MyTrait for T where T: SelectDsl<CountStar, BigInt, Output=SelectStatement<BigInt, CountStar, T>> {}

When writing <T as AsQuery>::Query: SelectDsl I seem to have better luck
