- rewrite
  
  public Expression rewrite(Object obj, Translator tr)
  
  Re-write an expression that is an "application" of this Syntax object.
  
  Parameters:
  
  obj - the arguments to this "application" (i.e. the cdr of the macro/builtin invocation)
  
  tr - the Translator that provides context
  
  Returns:
  
  the re-written expression
- rewriteForm
  
  public Expression rewriteForm(Pair form, Translator tr)
- scanForm
  
  public void scanForm(Pair st, ScopeExp defs, Translator tr)
- scanForDefinitions
  
  public boolean scanForDefinitions(Pair st, ScopeExp defs, Translator tr)
  
  Check if a statement is a definition, for initial pass. Semi-deprecated - should convert calls to use scanForm.
  
  Parameters:
  
  st - the statement to check
  
  defs - where to add Declarations for found definitions
  
  tr - the compilation state
  
  Returns:
  
  true on success
