Component‐private traits for unwrapped function types.

== Synopsis

Declared in `<bslalg_nothrowmovableutil.h>`

== Description

Do not use. This specialization is for function types that are not wrapped. This specialization is NOT for function pointers or function references.

`UnwrappedType` is an object type, and is thus the decayed version of `TYPE`, i.e., a function pointer. Since `unwrap` always returns a reference, this decay means that, `unwrap(f)` will not compile if `f` is a function or reference to function. However `UnwrappedType pf = f;` will work whether `f` is a function or not.
