I am having an issue with a macro that I am not managing to solve. The code is messy, but I will try to make clear the issue.
I have the source code [here](https://github.com/mantielero/ipopt.nim/tree/master/src). When I compile this code, the last lines displayed (from expandMacro): echo [repr [[2.0 * x[3]], [x[3], 0.0], [x[3], 0.0, 0.0], [2.0 * x[0] + x[1] + x[2], x[0], x[0], 0.0]]] created by [this lines](https://github.com/mantielero/ipopt.nim/blob/9967dc72130a45e8d6a675439f174cf24a01c941/src/ipopt.nim#L474). Basically, obj_hess is typed as seq[seq[NimNode]] and contains a triangular matrix: [ [2.0 * x[3]], [x[3], 0.0], [x[3], 0.0, 0.0], [2.0 * x[0] + x[1] + x[2], x[0], x[0], 0.0]]] The problem is when I reference a particular line or item. If I do the following in line 474: echo repr `obj_hess`[0] I get the following error: /home/jose/src/ipopt.nim/src/ipopt.nim(547, 3) template/generic instantiation of `problem` from here /home/jose/src/ipopt.nim/src/ipopt.nim(323, 15) Error: type mismatch: got <array[0..1, Number]> but expected 'array[0..0, float]'
