Oh, thanks a lot. Seems like 'auto' margins treatment were added recently.
Interesting. Close enough, indeed.

Do you know what is flex value of 'auto' in margin-left:auto ?

In other words: what would be computed
values of margins/width here:

.flex > div {
  margin-left: auto;
  width: auto; /* or shall it be flex-grow:1 ? */
  margin-right: auto;
}

And things like:

  margin-left:1*auto;
  margin-right:2*auto;

seem like still not there yet.
