The following two expressions using } are equivalent. I would argue that the first is a more expressive use of the notation because it reveals the intention to change the variable more clearly.
However, the side effects (space used) are very different. xxx=.1000000?10000000 7!:2' xxx =. xxx 2 3 }~ 999' 8391296 7!:2' xxx =. (999) 2 3 } xxx' 2432 Could }~ be treated specially to eliminate this difference?
