I couldn't find much documentation about SLLs. It is hard to know 
exactly what SLLs supported and how they used to work. I believe SLL 
loading was part of the VM, not the image. If so, I don't know if, for 
example, they could handle class reshaping at all.

DynamicCuisLibraries are fully implemented in Smalltalk. One advanced 
feature is that if the image that builds a DCL has a different shape for 
some class as the image that loads it, the load procedure computes the 
union of the instance variables known by each, and adjust any ivar 
access in CompiledMethods so everyting works as expected. I believe that 
neither SLLs nor Parcels could do this.

Please take a look at the included tests.
