public class ElementGet extends AstNode
foo['bar'] or
 foo[2].  This is sometimes called an "element-get" operation, hence
 the name of the node.
 Node type is Token.GETELEM.
The node bounds extend from the beginning position of the target through the closing right-bracket. In the presence of a syntax error, the right bracket position is -1, and the node ends at the end of the element expression.

 Note: if the parser was in error-recovery mode, some AST nodes may have
 null children that are expected to be non-null
 when no errors are present.  In this situation, the behavior of the
 toSource method is undefined: toSource
 implementations may assume that the AST node is error-free, since it is
 intended to be invoked only at runtime after a successful parse.
