This is interesting, but it is the reverse of the previous
functionality.  What I had was:

#+MACRO: data Snippet of awesome text that changes sometimes.
#HTML: <p class="awesome">{{{data}}}</p>

Your sample code is the equivalent of this, kind of:

#+MACRO: foo <p class="awesome">$1</p>
{{{foo("Snippet of awesome text that changes sometimes.")}}}

The original intent was to avoid changing the snippet of awesome text
everywhere it appears.

Your code actually does not actually work with my Org
(7.9.3e-1032-g791a8d). It asks me: "Evaluate this org code block
(html-foo) on your system? (y or n)" and is not happy with either
answer, exporting nothing.

This almost works, I think ...

#+name: snippet-awesome
#+begin_src org :exports results :results raw
Snippet of awesome text that changes sometimes.
#+end_src

#+HTML: <p class="foo">
#+CALL: snippet-awesome :results raw
#+HTML: </p>

... except that it doesn't actually export anything, and changing
:exports to none doesn't help.  And neither does removing the :results
raw from the call.

If it did work, it would be closer to what I had.  Not perfect, but
closer.

Maybe a babel specialist can say what is wrong with my attempt, or maybe
it's a bug.

I hope you won't spend more time on this.  You've spent way too much
time on my trivial problems already.

Thanks again!

Terry
