#evaluate directive is wiping out macros
----------------------------------------

                 Key: VELOCITY-591
                 URL: https://issues.apache.org/jira/browse/VELOCITY-591
             Project: Velocity
          Issue Type: Bug
          Components: Engine
    Affects Versions: 1.6
         Environment: JDK 1.5
            Reporter: Jonathan Tew
            Priority: Critical


I think I've found a problem with the new #evaluate directive in 1.6.  It seems 
like a call to #evaluate is causing the macros that have already been defined 
to be cleared.  Here is a test template to demonstrate:

#macro (test $t)
  test: #evaluate($t)
#end

#macro (test2 $t)
  test2: #evaluate($t)
#end

#evaluate("Will Clear Macros")

#test("hi world 1")
#test2("hi world 2")


-------------------------------

My overall major goal is to have a template be able to render other VTL that is 
pulled from objects.  The problem with the RenderTool is that it doesn't share 
the same macros as the parent.  That's why I'm trying to go down the route of 
using the new #evaluate directive since in theory both the macro and context 
are shared.
