Yes.

Here is Simon Urnbanked on May 26, but I don't right now find this on gmane
either. It is in response to a new thread which itself followed on something
where Brian gave equally clear recommendation for .Call against .C:

    That is bogus - .C is inherently unsafe wrt vector lengths so talking
    about safety here is IMHO nonsensical. Your "safety" relies on bombing
    the program - that is arguably much less safe than using checks that
    Brian was talking about because they are recoverable. You can argue
    either way, but there is no winner - the real answer is use .Call()
    instead.

"The real answer is use .Call instead" works for me.
