+* SUMMARY: A class A should not see a global variable if the latter
+* is defined too late. But what exactly is "too late"?
+*
+* In this test, the global variable in question is "objB". To define
+* it "too late", it would not be enough to have 'var objB = etc.'
+* as the last line of the script. All top-level var statements
+* are "hoisted" and processed FIRST (before any assignments).
+*
+* So we define objB on the last line with a 'var'. That should make 
+* the test pass. The fact that objB is an object variable is immaterial.
+* 
+* This test is just like test 'class-018-n.js', except on this point.
+* Class-018-n.js omitted the 'var', to generate an exception -
