So when they designed it, it wasn’t that bad for simple cases. However, with more complex nested lists, there isn’t a clear data flow, it jumps from one place to another. Especially the first term is problematic. It’s not beneficial at all for the modern IDE based development. So at the end, this is a better list comprehension in this sense:

`[state_dict.values() for mat to mat2 for row for p to p/2]`

Or similar, where data flow is 1->2->f(2)->3->4->f(4). Where right now it is this lovely mess with one more repeating term:

`[p / 2 for mat in state_dict.values() for row in (mat 2) for p in row]`

Where the flow is f(4)->2->1->3->f(2)->4->3

This is not just a Python list comprehension problem obviously. The simple for… in… has a similar problem. It’s only better, because the first term `p/2` is at the end.
