The "Object-Relational impedance mismatch" is not a result of the supposed fact that "no programming language lets you deal with relational data sanely in code", its a result of the fact that industrially popular object-oriented languages, of the time when the term was coined, did not align well with the data model supported by then-existing relational databases, and vice versa.
