[~kenn] Can I take this one? Actually, I did a refactoring and some tests are 
failing because of this short-circuit. I'll try to fix it.

> In {{BeamSqlFnExecutor}} there is a pattern where first the returned 
> expression is assigned to a variable {{ret}} and then after a giant switch 
> statement the validation is invoked. But there are many code paths that just 
> call {{return}} and skip validation. This should be refactored so it is 
> impossible to short-circuit on accident like this.
