BTW this seems hard to implement well without invasive changes to the desugar logic.

Nontrivial case: the list is `{std::string}`, the type is `std::string*`.

Pathological case: the list is `{std::string}`, and the type is `pair<std::string*, size_t>`. Desugar yields `pair<basic_string<char>*, long long>`, desired output is `pair<std::string*, long long>`.
desugarForDiagnostic needs to exclude the first TP from desugaring based on it matching a string, but we don't stringify all the intermediate types.
