given js> with(o) { eval("var foo = 4"); } by section 10.1.4, we shouldn't see foo defined on the with object o. But on rhino, it seems to be- js> foo ReferenceError: "foo" is not defined. js> o.foo 4 (thanks to Waldemar for clarifying the correct behavior in this case.)

So should the rule be: When executing an eval() inside a with statement, define any variables resulting from var statements in the first non-with, non-catch scope. So another test for this is try { throw 3; } catch (e) { eval("var bar = 6"); } print(bar); which should print 6.
