[clean-list] suggestion for htoclean and arrays

You could try Clean's CLAS-library, inspired on Blas, so I read. CLAS is
able to address sub-arays: slices.

There is an occasion where Clean allows you to open unique
sub-environments: From the *Files environment you can open an individual
*File, and then independently read and update various files in parallel.
This behaviour is not generally available though. If you have a unique
tree-structure, you cannot open various unique sub-trees and change them in
parallel.

Well, you CAN if you try hard. I once managed to do so by copying unique
nodes through code { } statements in Clean. But that was the bleeding edge
and I lost laziness on the way. Maybe one time Clean will let you routinely
'open' and 'close' arbitrary unique substructures.
