For security reasons evaluation is not turned on by default.  The
relevant chapter of the manual is a very good resource [1].

You can insert code-block templates by typing <s TAB, and there exists
other methods of expressing code blocks (e.g., inline code blocks).

If you do want to experiment with different syntax, it should be fairly
easy to write a function which parses some sparse code syntax near the
point and then calls existing org-babel-execute functions to run the
code.  For example the following function will check to see if the
current line starts with a "$", and if so, it will run the line in your
shell and insert the result immediately following the line.

    ;; -*- emacs-lisp -*-
    (defun sparse-execute ()
      (interactive)
      (save-excursion
        (goto-char (point-at-bol))
        (if (string= (thing-at-point 'char) "$")
            (let ((result (org-babel-execute:sh
                           (substring (thing-at-point 'line) 1) '())))
              (goto-char (point-at-eol))
              (open-line 1) (forward-char 1)
              (let ((beg (point)))
                (insert (format "%s" result))
                (org-babel-examplize-region beg (point))))
          (error "this line doesn't look executable"))))

Cheers,
