	English Inserts `obj` in the table if and only if there is no element in the table with an equivalent key, and then invokes `f1` with a non-const reference to the newly created element. Otherwise, invokes `f2` with a reference to the equivalent element; such reference is const iff a `*_cvisit` overload is used. 304/10000 · 304
