This also lead to the creation of the categories glvalue (generalized lvalue) which are lvalues and xvalues and prvalues (pure rvalues) which are rvalues that are not xvalues. [6] This type of reference can be applied to all r-values including non-l-values as well as l-values.
L-value, L value or lvalue may refer to: In astronomy, a measure of brightness of a lunar eclipse on the Danjon scale; L-value (computer science), denoting an object to which values can be assigned; In number theory, the value of an L-function; In space physics, the value assigned to an L-shell, a particular set of planetary magnetic field lines
Rvalue references can also be modified only under certain circumstances, being intended to be used primarily with move constructors. Due to the nature of the wording of rvalue references, and to some modification to the wording for lvalue references (regular references), rvalue references allow developers to provide perfect function forwarding.

Rvalue references to cv-unqualified type template parameters of that same function template or auto&& except when deduced from a brace-enclosed initializer list are called forwarding references (referred to as "universal references" in some older sources [2]) and can act as lvalue or rvalue references depending on what is passed to them.
