[O] [bug] Macro expansion not recursive

[Sebastien Vauban]

Hello,

It was said that "Macro expansion is already recursive: the template can
be another macro."  Though, my example does not work: the second macro
call is exported almost "verbatim".

--8<---------------cut here---------------start------------->8---
#+MACRO: highlight @@html:<span style="background-color: $1;">$2</span>@@
#+MACRO: hl {{{highlight(#FFFF00,$1}}}

{{{highlight(yellow,This is important!)}}}

{{{hl(This is important!)}}}
--8<---------------cut here---------------end--------------->8---

Am I missing something?

Best regards,
  Seb
