"WebChisel3 API may implement the reductions as folds with initial values and we document it as such. I'd propose then that chisel3.strict doesn't include andR and instead uses foldAndTrue and foldOrFalse. For (4), what I mean is val foo = bar.andR could emit as: red (a ## b) === red (red (a) ## red (b)), so xorR should return 0 in this case. edited " - Chisel uint width
