gnu.expr
Class PushApply

java.lang.Object
  gnu.expr.ExpWalker
      gnu.expr.PushApply

All Implemented Interfaces:

SourceLocator, org.xml.sax.Locator

public class PushApply
extends ExpWalker

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.
