rewrite

public Expression rewrite(java.lang.Object obj,
                          Translator tr)

Description copied from class: Syntax

Re-write an expression that is an "application" of this Syntax object.

Overrides:

rewrite in class Syntax

Parameters:

obj - the arguments to this "application" (i.e. the cdr of the macro/builtin invokation)

tr - the Translator that provides context

Returns:

the re-written expression

rewrite

                    TemplateScope templateScopeRest)

Higher-level constructor, that does the re-writing.

Parameters:

formals - the formal parameter list (or symbol)

body - the body of the procedure

tr - the (Scheme) Translator
