Looks great!! I think there were two extensions for this floating around, which are now possible to have - one (I think suggested by Gabor?) was to have by=.EACHI work with other types of i-expressions - simplest example would be d[, j, by=.EACHI] doing the same as d[, j, by = 1:nrow(d)], and another one was to be able to combine .EACHI with other by's, i.e. have smth like d[i, j, by = list(.EACHI, somecol)] (this one is somewhat more exotic and doesn't have an existing analogue afaik). Not sure if an FR for these exists.
