i have been hitting my head against a wall trying to get a simple math example working with jit.expr. as you can see on the left i have the expr object working on a single number. the idea is to run this expression in a matrix, but in setting up a simple example (on the right) i am having a fundamental issue, i would like to eventually get this into gen, but this is just my first step. what am i doing wrong? i would think the example on the right would take the cell value and add 2 but as you can see it is not working that way. any help would be much appreciated.
