I would not give them up. My only point was that for some runtime-critical parts (about 1-10% of the code) it would make sense to allowing OPTIONAL type-restrictions in order to make life easier for a possible optimizer in future. Please check out my postings 151150 and 151160 also... Best regards, Christian
