public class MemberAccess
extends Expression
implements IFieldAccessExpression, IHasOperatorLineNumber

Represents a member access expression in the Gosu grammar:

 member-access
   <root-expression>.<member>
   <root-expression>[member-name]
 

 root-expression
   <bean-reference>
   <type-literal>
 

 member
   <member-access>
   <identifier>
 

 bean-reference
   <primary-expression>
 

 member-name
   <expression>
