     9  * SUMMARY: with(...) { function f ...} should set f in the global scope

    10  * See http://bugzilla.mozilla.org/show_bug.cgi?id=184107

    11  *

    12  * In fact, any variable defined in a with-block should be created

    13  * in global scope, i.e. should be a property of the global object.

    14  *

    15  * The with-block syntax allows existing local variables to be SET,

    16  * but does not allow new local variables to be CREATED.

    17  *

    18  * See http://bugzilla.mozilla.org/show_bug.cgi?id=159849#c11
