OK. Thanks for the patch.

PS: You wrote for the RFC patch:
"Array intrinsics *do not work at all*. This is a limitation of the 
array descriptor structure, which I cannot overcome by myself."
Wouldn't it work to use a patch as the following - or have I missed some 
fine print? I think we have enough bits to fit 8 DTYPEs - and without 
the following patch I only count 7.
