If you like that, you'll love what happens when you hit ALT-period in
bash -- it recalls and displays the value of last argument to the
previous command.  Subsequent uses of ALT-period recall the last
argument to previous commands.

You might also find the environment variable $_ useful.  It serves the
same purpose as !$, but works even if you've disabled bang-expansion.
