ℹ️ This is the second blog post discussing dynamic-derivations in Nix. Checkout the first part An early look at Nix Dynamic Derivations if you want a primer on the experimental feature. I’m still in love with the experimental feature dynamic-derivations in Nix 🥰, but following my earlier post I had read comments from readers that

Suppose that you want to reorder, arbitrarily, the bits in a 64-bit word. This question was raised on Twitter by @experquisite. Formally, you might want to provide, for each of the 64 bit position, an original bit position you want to copy. Hence, the following code would reverse the bit order in your 64-bit word:
