A predefined function Slice for all (at least for all one-dimensional) 
array types would be OK. Having to instantiate a generic or to write a 
slice function on ones own each time one needs a slice would clutter the 
code ...

There is a simple reason why I didn't address that part of your posting: I 
don't have a strong point in favor of slices as l-values.

I haven't been aware that l-value slices are so difficult to implement, 
and I wouldn't mind to put them away.

Thank you!
