Are you sure Cog doesn't care? I think it does. From what I can see in Cog
code the entry point to inline #class is from the bytecoodes. If you see
initializeBytecodeTableForClosureV3
...
#(1 199 199 genSpecialSelectorClass needsFrameNever: notMapped 0). "not
mapped because it is directly inlined (for now)"
...
so if you use a the normal bytecode for #class then I think #class is not
inlined in machine code. At least from my tests I noticed that.
I guess you're right.

Another thing that you should add (besides tests of course) is
SmallInteger >> #pointsTo: which should return false. Also make sure that
pointer tracing tools use #pointsTo:. In Squeak I found that some of them
"reinvented" this method...
