(in 0.8, 0.0 != None).

this is documented behaviour for metakit backend if
BACKWARDS_COMPATIBLE is set (default).

test case needs to be fixed.  better yet, both
BACKWARDS_COMPATIBLE and not BACKWARDS_COMPATIBLE modes
should be tested.

discussion: change default setting to disable
compatibility mode?

at the least, we may move 'newnum' test at the end of test
case to have it fail after all other tests pass and document
this failure as a known bug.
