| 2026-01-22 06:13:25 +0100 | <probie> | `pos ctx` gives you the element under focus (not used in ncf's thing), and `peek x ctx` "inserts" `x` into the context |
| 2026-01-22 06:11:45 +0100 | <probie> | holesOf takes a traversal and a thing to traverse and gives you a list back, where for every traversed element, you get a "context" of what was around the element |
| 2026-01-22 06:09:26 +0100 | <haskellbridge> | <iqubic (she/her)> Right, but how the hell are you just reversing only one element at a time? |
