Hi Saso,

I'm very happy to hear that. I just want to let you know I have  
implemented NSExpression, NSPredicate, NSCompoundPredicate and  
NSComparisonPredicate except raw predicates parsing support related  
to -initWithFormat: method. I worked on it one month ago, but I was  
away from home at this time and I forgot the hard disk where I stored  
this stuff when I came back; however I should be able to recover this  
hard disk in one or two weeks.

For KVO, Gregory Casamento was planning to work on it, he talked  
about it on gnustep-dev list.

May be I or somebody else can help you…

Very cool.

Thanks,
