[00:15:40] Looks like you can't run the impl from the "Try this implementation" section if a function has no connected implementations. On a function with an existing implementation I can still try my own (unconnected) impl. [02:59:12] I also just found https://www.wikifunctions.org/view/en/Z11328. Another hamming distance function (I was only looking at the catalogue, I found this in the full list of functions). The one I published does work for unequal binary strings (as they get converted and xor'd) and has a composition implementation. Should I just rename the function [02:59:13] 'hamming distance for bit strings'? Since the existing one would fail for 101 and 0111 for example
