Re: weird macro params issue

Just a quick heads up that I'm making some progress with this in the  
2.4 codebase. There are four cases arising from the four possible  
combinations of (positional,named) x (positional,named) in declared  
parameter list and invocation parameter list; I've written the code  
for 2 of them so far.

An immediate additional benefit is that defaults will also be  
processed for TemplateMethodModels, TemplateDirectiveModels and  
TemplateTransformModels that declare them in their @Parameters  
annotation, something that as far as I can see wasn't supported  
previously at all.
