Re: [sv-ec] Invalid example of srandom - mantis 1391

method_call_root was not just added to handle 'this' and 'super', but to
support method calls for any expressions that yield handles allowing
such calls.

An example like the following from 7.11

   p.next.next.next.val

would still be legal as 

   p.next().next().next().val

Otherwise one could only chain through a sequence of handles using
default argument values.

p.s. According to Table 8-3, dot is an operator.

Brad,

ERR-47 was added to allow things like this.method_call() and
super.method_call(). It still does not make '.' an operator.
