lastEvalTopCalled_

private static boolean lastEvalTopCalled_

This indicates whether last call of "eval" was at the top scope (i.e. "eval()") or not (i.e. "scope.eval()"), as each one has different behavior.

Ideally, we should have "eval" at top scope and we use Context.FEATURE_DYNAMIC_SCOPE, but it will complex the code.

The current implementation sets this value to true when "eval" is called, and false on "something.eval()"

bind

public static Scriptable bind(Context cx,
