Just released addon: format/zulu-bare . This is like format/zulu-lite except that it loads the so-called *2* verbs only, in their "bare" (uncorrected) versions. It comes with its own Lab (zulu-bare.ijt).
It's of minority interest only. Unless you want extreme performance, I'd recommend format/zulu-lite, or format/zulu (to give you the sandbox too). If none of this means much to you, run the lab (zulu.ijt) which comes with: format/zulu.
