Re: [Laszlo-dev] any idea why lzNode is trying to bind a name on an instance which is a method name ?

[P T Withington]

This is because there is a constraint in the base class and then in  
the instance we are trying to install a new constraint.  Either we  
need to bite the bullet and make instances be classes now, or maybe we  
should back off and not make the constraint methods be methods, just  
leave them as closures so they can be 'overridden' in instances by  
setting (rather than subclassing).  I'm trying to think what the most  
expedient change would be...
