= Variable entity =

Variable entities hold all the information about variables, such as binding expressions, scopes etc.

== Initial selector ==
* {{{@var}}} to start a query with a variable entity, use this selector to refer to the selected variable.

== Selectors == 
The following selectors can be used on variable entities.

''After the name of the selector between parentheses you can find the type of the elements in the resulted set.''

* {{{refs}}} (''expression''): returns the set of expression entities that refer to the variable.
* {{{bindings}}} (''expression''): returns the top-level expression that binds the expression. It is always a pattern expression, e.g. an argument of the function, or a pattern in a case construct. If the binding expression is ambiguous, every possible binding expression is returned.
* {{{fundef}}} (''function''): gives the function entity which contains the binding (definition) of the variable.

== Properties == 
There is only one property for a variable:
* {{{name}}} (''atom, string''): returns the name (identifier) of the variable.
