In lieu of invoking the supersequent (I couldn't figure out why imp_getBlock() wasn't working from the original implementation)...

Shouldn't this also check for NSDictionary's and recursively remove nulls there as well?

I would use a much higher constant for NSJSONReadingFuckNSNulls than (1UL << 3). If Apple adds a reading option il will most probably be (1UL << 3) but it might not be Fuck NSNulls.

i love you. i first come about nsnull today and spent the last 5 hours trying to figure it out. eventually after i did i just searched google "fuck nsnull". thank you for this.
