[Cuis-dev] [Ann] Serialization of BlockClosures

[Juan Vuletich]

Oh, apologies. I thought those were harmless and didn't even comment 
about them. You can get by by removing #3889 and #3890 until we 
understand and fix.

The idea is to fix things like

Color red select: [ :v | v > 0.5 ]

This shouldn't answer an instance of Color, but of the closest 
superclass that can have instances of any size. The same happens for 
many other classes in optional packages. How is this affecting your 
code? I guess you have ArrayedCollection classes that answer a non-zero 
value to #numElements, but their #species should be the class, right? 
What would happen if a #select: answers a smaller instance? And more 
important, what else are we using #species for?

Thanks,
