What do you mean with "potentially wasteful"?
Excess calls to copy constructors?
Evaluation of an expression the result of which might not be used.
defaultValue could be anything: a literal, an lvalue, a result of a
function call...
IMO you are overenginering this. defaultValue will most likely be
something distinct such as compile-time constant.
