Put them (after emacs -Q) in a buffer, visit the buffer, `eval-buffer'. But the
way you used will work also. The key, however, is the last line above: evaluate
(buffer-list) from the minibuffer - e.g. during M-x or C-x C-f. Use `M-x M-:',
not just `M-:'. (That was the point of setting `enable-recursive-minibuffers' to
t.)

The real use would be from a command bound to a key in a minibuffer keymap. If
it examines the `buffer-list' the result is very different in Emacs 23 from
Emacs 20, 21, and 22.
