Can you explain what the colon in "$commit^{:nth(3)/foo}" is doing?
Are we declaring anything that begins with ':' is a magic inside ^{...}
construct?
I do not think nth($n) without specifying where to start (iow, what the
current ":/foo" implementation does but with "three levels deep") makes
any sense, but because the main point of your argument is that we can have
modifies other than nth($n) that may make sense in such a context, I would
want to make sure anything we come up with is extensible to that syntax.
On the "starting from any ref" front, I think "!" (as in ":/!some magic")
was the introducer we reserved for such a magic some time ago, so perhaps
on the "starting from this commit" side, "^{!magic/foo}" may be more
appropriate?
