GNU APL 1.4: Parallel / multicore implementation of primitive functions and operators

Regarding this part, it does indeed look very interesting.

This reminded me of something I was thinking about one night before going to sleep (to take it with whatever amount of NaCl you want) after having run some simple matrix operations in a profiler.

I realised that for a simple operation such as  +/25000000⍴1, most of the time seems to be spent updating the reference counts for the individual cells. Is this correct?

Is there any obvious way this could be optimised? Say, for example, by creating a specialised array type that does not hold cells but rather raw numbers?
