[closer-devel] Re: Layered function troubles

[Pascal Costanza]

Hi Nick,

Thanks for finding the mistake yourself. ;)

It would indeed be nicer if a define-layered-method could  
automatically generate a proper layered function, not an incomplete  
one as is currently accidentally the case. However, I haven't yet  
figured out how to make this work. I will try to think about a  
solution...
