I remember back in '96 I made a search for those languages and all letters were defined on wikipedia, yes I checked all 26 of them, since then some have merged, morphed, or died, a few went from opensource to commercial, then I lost track after a while, the one that seemed to have big data structure handling was K, but its syntax was horrible and complicated but very short, I hope it has improved, I suggested K for POV-Ray and I got flamed by 1 of the devs of it no less, among others, when I tried to discuss the idea on their newgroup, damn that was a bad call, but I honestly thought it used a lot of data back then
