Namespace meta

Description

Namespace for our meta-programming facilities.

This namespace also hosts the meta-programming facilities designed before C++ had constexpr.

	constant	Wrapper for (integral) constant expressions.
	has_sign	A `meta::constant` yielding whether a type allows negative values.
	padding	Metafunction yielding the number of padding bits of a type.
	precision	Metafunction yielding the precision of a type.
	select	Compile-time selection between types.
	select_	Like `select`, but with the condition represented as a `bool` value, not a type.
	unqualify	Metafunction to get the corresponding unqualified type of its argument.
	width	Metafunction yielding the width of a type.

Tells whether a type uses a two's complement representation.
