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

scanForDefinitions

public boolean scanForDefinitions(gnu.kawa.util.Pair st,
                                  java.util.Vector forms,
                                  ScopeExp defs,
                                  Translator tr)

Description copied from class: Syntax

Check if a statement is a definition, for initial pass.

Overrides:

scanForDefinitions in class Syntax

Tags copied from class: Syntax

Parameters:

st - the statement to check

form - where to append the (possibly-modified) statement

defs - where to add Declarations for found definitions

tr - the compilation state

Returns:
