Argh - sorry. That shouldn't have been on of course. I did some
benchmarking and must have forgotten to disable it. It is ment to
access the signature array faster. The type of the signature array is
known as Parrot is constructing it. The flatten code must of course be
outside the range of this define.
Make sense. Thanks for explaining.
But it's not clear to me that it would ever be worth optimizing
VTABLE_elements calls, even for the signature array. Seems to me that
it's called exactly twice per call/return sequence, true?
Thanks a lot for spotting this and the tests, applied - r10385.

No problem; glad to be useful. If I get a chance, I'll try to work up
more call/return tests involving :slurpy and/or :flat.
