Two strict mode issues #1007

Hi,

I run my tests after resolution of #980, most errors are gone, great, thanks.

Now there are still only 2 failures from 123 tests, both regard strict mode, both should fail:

1. {"a":[ ,4,null,8]} is parsed as [null,4,null,8]
2. {"a": 0.} is parsed as 0

I apparently fixed both on my machine, I tried to provide two p.r.

Thanks
