check_insecure_method(obj, msg_id) public

Check that a method is callable via dRuby.

obj is the object we want to invoke the method on. msg_id is the method name, as a Symbol.

If the method is an insecure method (see #insecure_method?) a SecurityError is thrown. If the method is private or undefined, a NameError is thrown.
