Hi all,

      The new parser supports safe index now, which is proposed by Paul King
:)

      Here are some example code:

assert null == null?[1];
assert null == null?[1]?[1, 2];
assert null == null?[1]?[1, 2]?[1, 2, 3];

def a = null;
assert null == a?[1, 2];

def f() {return null}
assert null == f()?[1];

       More information can be found at the safeIndex branch of
groovy-parser
project(https://github.com/danielsun1106/groovy-parser/tree/safeIndex)

       Any thoughts?

       BTW, the antlr4 branch of apache/groovy is very old, I am going to
try to update it with the master.

Cheers,
Daniel.Sun
