We have

dyad (<"1@[ { ])

which is backed by special code and gives a good way to read scattered 
values from an array.  I am looking for a comparable way to 
scatter-write to an array without boxing all the points.

I can't think of one, and I wonder whether we should define

dyad m}

where m is numeric of rank 2 or higher, as

(<"1 m)}

An incompatible change, but perhaps no one would notice.

Alternative would be to back dyad (<"1 m)} with special code, but that 
would be a parser change.
