I have not followed the discussion nor have I fully read the patch, but 
what's the reason for allowing ELEMENTAL functions? I understand the 
PURE and the implicitly pure part. But without looking at the 
scalarizer, I would assume that the same reasons which speak against 
non-elemental impure functions should also speak against IMPURE 
ELEMENTAL functions, don't they?
