#### 1.4.2 Variable References

An expression consisting of an identifier (see Identifiers) is a variable reference; the identifier is the name of the variable being referenced. The value of the variable reference is the value stored in the location to which the variable is bound. An error is signalled if the referenced variable is unbound or unassigned.
