template < class T > concept bool DefaultConstructible = Constructible<T>;		(ranges TS)

The DefaultConstructible concept provides a shorthand for the common case when the question is whether a type can be constructed with no arguments.

Constructible	specifies that a variable of the type can be constructed from or bound to a set of argument types (concept)
