C++ Value Categories Explained

Text on the meme

glvalue lvalue xvalue prvalue rvalue has identity (i) i&&!m i&m !i&m is movable (m)

What it means

A Venn-style diagram explains C++ value categories using identity and movability: glvalues include lvalues and xvalues, while rvalues include xvalues and prvalues. The joke is the intimidating complexity of C++ terminology and classification, making it useful as a reaction to confusing or overly complicated C++ explanations.
