// keeps conforming compilers (those implementing proper 2-phase
// name lookup for templates) from complaining about incomplete
// types in situations where it would otherwise be inconvenient or
// impossible to re-order code so that all types are defined in time.

// One such use is when we must return an incomplete T from a member
// function template (which must be defined in the class body to
// keep MSVC happy).
