 Promotion is a concept that we have already explored in other contexts. Psyco is
 a run-time specialiser for Python that uses promotion (called ``unlift'' in
 \cite{DBLP:conf/pepm/Rigo04}). However, Psyco is a manually written JIT, is

 Promotion is invoked with the use of a hint as well:
-\texttt{v2 = hint(v1, promote=True)}.
+\lstinline{v2 = hint(v1, promote=True)}.
 This hint is a \emph{local} request for \texttt{v2} to be green, without
 requiring \texttt{v1} to be green.  Note that this amounts to copying
 a red value into a green one, which is not possible in classical
