This is a port of the generation bits of stephenmathieson/node-tlds to Go. The original package suffers from the issues discussed in “npm & left-pad: Have We Forgotten How To Program?”, including depending on multiple third-party packages that are utterly unnecessary — even in JavaScript/Node.js.

I wanted to provide something more reliable, with no dependencies outside the standard library.
