When designing a language, the concepts of "lvalue" and "rvalue" come
into play. An "lvalue" is an expression that can be assigned to (that
can appear on the "L"eft hand side of an = sign), and an "rvalue" is
anything that isn't an lvalue (that is, something that can only appear
on the "R"ight hand side of an = sign).

Overloading "rvalue" to mean "real value" might cause some semantic
dissonance in those reading the code.
