Operators are tokens that trigger some computation when applied to variables and other objects in an expression.

Assignment

Bitwise

C++ specific

Comma

Equality

typeid

All operators can be overloaded except the following:

- . C++ direct component selector
- .* C++ dereference
- :: C++ scope access/resolution
- ?: Conditional

Depending on context, the same operator can have more than one meaning. For example, the ampersand (&) can be interpreted as:

- a bitwise AND (A & B)
- an address operator (&A)
- in C++, a reference modifier

Note: No spaces are allowed in compound operators. Spaces change the meaning of the operator and will generate an error.
