The dyad`i.` family of facilities has been improved:

| `x i. y` |  | also`i:` ;`` for floating point or general integer list`x`
| `x i.!.0 y` |  | also`i:` ;`` for boxed`x` and`y`
| `(i.<./) y` |  | also`i:` or`>.` ;`` for integer and floating point list`y`
| `m&i. y` |  |
| `-.&n y` |  |
| `e.&n y` |  |
| `x (e.i.1:) y` |  |

The first improvement`` (`i.` and`i:` for floating point and integer vectors) is minor, under 15% in time. Other improvements are more substantial; benchmarks demonstrating that are available by following the links above.
