* SUMMARY: with(...) { function f ...} should set f in the global scope
* See http://bugzilla.mozilla.org/show_bug.cgi?id=184107
*
* In fact, any variable defined in a with-block should be created
* in global scope, i.e. should be a property of the global object.
*
* The with-block syntax allows existing local variables to be SET,
* but does not allow new local variables to be CREATED.
*
* See http://bugzilla.mozilla.org/show_bug.cgi?id=159849#c11
