-// Written by Vicente J. Botet Escriba //
-// //
-// 1 The library provides the function template declval to simplify the
-// definition of expressions which occur as unevaluated operands.
-// 2 Remarks: If this function is used, the program is ill-formed.
-// 3 Remarks: The template parameter T of declval may be an incomplete type.
-// [ Example:
-//
-// template <class To, class From>
-// decltype(static_cast<To>(declval<From>())) convert(From&&);
-//
-// declares a function template convert which only participates in overloading
-// if the type From can be explicitly converted to type To. For another example
-// see class template common_type (20.9.7.6). -end example ]
