Another XLint suggestion

[Mark S. Miller <vlad!mark>]

XLint should check that all messages sent (member functions invoked)
from an object to itself be of the form:

	this->zip(...);

and not:

	zip(...);

We noticed this when we saw some alpha-4 code that violated this
convention.  To me, "zip(...)" sure looks like an invokation of a
global function.

Classify this suggestion as "cannot be generated from Smalltalk".
Thanks.
