<div dir="ltr">Looks great!!<div><br></div><div>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.</div>

Not yet, but yes NEWS says :
<pre style="text-indent:0px;letter-spacing:normal;font-variant:normal;text-align:left;font-style:normal;font-weight:normal;padding:0px;line-height:11.050000190734863px;text-transform:none;margin:0px 0px 1em;font-family:monospace;word-spacing:0px">
A "classic" option to restore the previous default behaviour is to be discussed and confirmed.</pre>
Maybe :<br>
<br>
options(datatable.bywithoutby = TRUE)<br>
<br>
is all that's needed. Will do.<span class="HOEnZb"><font color="#888888"><br>

Dear all,<br>
<br>
by=.EACHI is now implemented and available in v1.9.3 from
R-Forge.<br>
<br>
Please take a look at NEWS and see what you think :<br>
<a href="https://r-forge.r-project.org/scm/viewvc.php/pkg/NEWS?view=markup&root=datatable" target="_blank">https://r-forge.r-project.org/scm/viewvc.php/pkg/NEWS?view=markup&root=datatable</a><br>
<br>
Quite a few related bugs and feature requests get resolved by
this, still going through them updating NEWS and adding tests.
Thanks to all.<br>
<br>
The changes are very much up for debate and change at this
stage.<br>
<br>
Matt<br>
