java.lang.Objectgnu.expr.ExpVisitor<Expression,java.lang.Void>
gnu.expr.PushApply
public class PushApply
Re-arranges ApplyExp where the function is a LetExp or BeginExp. Optimizes ((let (...) body) . args) to (let (...) (body . args)). Optimizes ((begin ... last) . args) to (begin ... (last . args)). This helps optimize Scheme "named let" (and some other forms) by making it more likely the application will be to a known procedure. This optimization has to be done after Declarations are bound.
