It's buried in the FOR command, where you wouldn't dream of looking
for it.  Type "for /?" and read the part about the "for /f" option,
you will see that backticks are supported.  It is a trivial exercise
to make a FOR loop that loops exactly once and uses `foo`.

Still, it's not as advanced as the Unixy shell `foo` feature; in
particular, redirection in the `foo` command can be tricky or even
downright impossible.
