Actually, as I wrote last week, I wanted to be able to define something a little more complex, which turned out to be totally unpalatable by charmc:

readonly double weight[2*RADIUS+1][2*RADIUS+1];

Why would that be a reasonable thing to do for a readonly variable, one may ask? The reason is that this is an array that specifies the weights of a stencil. In my workload I allow different stencil sizes and different weights. But once defined, weight is a global constant. I let the user specify the constant symbol RADIUS, and use that to compute weight’s dimensions.

With the following change going through our review system, this will now work as written
