Groovy 2.5 @Macro ?

Hi guys,

giving the new Groovy 2.5 macro functionality a spin, and would have expected the code below to replace the "call" to nv(x) with the AST _expression_ created in the method, i.e. returning the name of the "passed" variable. Instead no macro magic happens, and the compilation accordingly fails with "groovy.lang.MissingMethodException: No signature of method: groovy.GroovyMacroSpike.nv() is applicable for argument types: (Integer) values: [123]":
import org.codehaus.groovy.ast.expr._expression_
import org.codehaus.groovy.ast.expr.VariableExpression
import org.codehaus.groovy.macro.runtime.Macro
import org.codehaus.groovy.macro.runtime.MacroContext
import org.junit.Ignore
import org.junit.Test

import static

class GroovyMacroSpike {
  void nvTest() {
    final x = 123
    assert x == 123
    assert nv(x) == "x"

  _expression_ nv(MacroContext ctx, VariableExpression variable) {
    return constX(variable.getName());
What is missing to make this work ?
