That has been in there since the beginning.  Try it; it works.  However,
SKsh (the new name) and ksh both recommend the $( ) syntax, for a few
reasons:

      1) Its easier to nest, since you don't have to backslash escape
         the inner backticks.  ie:

            `command1 \`command2 \` `
         vs
            $(command1 $(command2 ))

      2) In SKsh, the backtick notation is limited to the length of an
         SKsh token (currently 1023 characters).  There is no such
         limitation for the $( ) syntax.

Anyhow, I included the backtick style substition for compatibility with
the old bourne sh syntax.

PS - I have replied to *all* mail I've gotten about SKsh, but I have
     around a dozen replies which bounced.  My appologies to those
     people; if you sent me mail and didn't get a reply, that's what
     happened.
