About

C++ is a wonderful language. A collection of curious details:

A full-expression is not necessarily an expression at all.
void* is not a pointer-to-object but it is an object pointer.
Member pointers are not "pointers".
Default initialisation may leave the object uninitialised.
Rvalue reference variables are lvalues.
std::move doesn't move anything.
Function arguments cannot be arrays, but you can declare arguments to be arrays in which case they are "adjusted" to not be arrays.
