// all the others), the circularity is calculated based on the first problematic
// dependency of each field. So x's first problematic dependency is y, and y's
// first problematic dependency is x; therefore x and y are considered to have a
// circularity, and for error recovery their type is set to `dynamic`.
// Thereafter, z infers without problems.
