// Exercise outlives bounds for each of the following parameter/position
// combinations—
//
// • one generic parameter (T) bound inline
// • one parameter (T) with a where clause
// • two parameters (T and U), both bound inline
// • two parameters (T and U), one bound inline, one with a where clause
// • two parameters (T and U), both with where clauses
//
// —and for every permutation of 1 or 2 lifetimes to outlive and 0 or 1 trait
// bounds distributed among said parameters (subject to no where clause being
// empty and the struct having at least one lifetime).
//
// —and for each of tuple structs, enums and unions.
