 We recommend defining a new auxiliary function for processing function
 definitions.  This code is similar to the case for \code{Program} in
 \LangVec{}.  The top-level \code{explicate\_control} function that
-handles the \code{ProgramDefs} form of \LangFun{} can then apply this
-new function to all the function definitions.
