Hm, I probably should pull out the ones from the original article that I actually recognize (a couple of yours are from that). Mine was originally intended as a supplement, then it got out of control. I thought about `M` for matrix but after thinking I realized it's almost always `A` or something, with `m` as a dimension. That does remind me of `I` for identity though ... Ah, the editing window is closed, so I guess I have to extend it: f,g,h - function f - flags i - identity (e.g. of matrix) h,n/p,m - haystack, needle/pattern, match h,t - head, tail k,v - key, value of a map/dictionary l - location s - state t - token
