22//~ 20.3.4 Function template declval [declval]
23//~ 1 The library provides the function template declval to simplify the definition of expressions which occur as
24//~ unevaluated operands.
25//~ 2 Remarks: If this function is used, the program is ill-formed.
26//~ 3 Remarks: The template parameter T of declval may be an incomplete type.
27//~ [ Example:
28
29//~ template <class To, class From>
30//~ decltype(static_cast<To>(declval<From>())) convert(From&&);
31
32//~ declares a function template convert which only participats in overloading if the type From can be
33//~ explicitly converted to type To. For another example see class template common_type (20.7.6.6). �end
34//~ example ]
