> In the Groovy in Action book, chapter 8.4.5 says 
> {quote}Category method names can well take the form of property accessors (pretending property access), operator methods, and GroovyObject methods. MOP hook methods cannot be added through a category class. This is a restriction as of Groovy 2.4. The feature may become available in later versions.{quote}
> It interpreted this as meaning that I can add GroovyMethods (getProperty,
> getMetaClass, invokeMethod , setMetaClass and setProperty)  to a class using categories but not
> methodMissing or propertyMissing (which I think they call MOP hook methods in the GINA book).
> But when I tried to add invokeMethod using a category the change has no effect, adding missingMethod does not work either see attachement. 
> I see that methodsMissing/ propertyMissing via category was probably never supported noted in GROOVY-3867. But the Groovy in Action paragraph makes me think that invokeMethod et al were supported at some point.
