It may just be me, but I tend to think of a computer language as a
tool for directing computers to perform specific actions. Do we talk
about the expressiveness of a spade?
There's a similar concept in the 'possible uses' of a tool (a spade is
an excellent tool for digging the garden, but you wouldn't use it to
clean your teeth; you *could* use a toothbrush to dig the garden, but
you wouldn't if a spade was available). Similarly with computer
languages - some are better for certain tasks than others, but I don't
think 'expressiveness' is the way to describe that.
