immediateByteSubclass: ?

Hi 

with guille we are working on a class parser and our game is to make sure that we can parse all the crazy class definitions among which 

variableWordSubclass:

ephemeronSubclass:

weakSubclass:

variableByteSubclass:

variableSubclass:

immediateSubclass: 

subclass: aSubclassSymbol  layout:

And we found this method definition and it has no senders and we wonder if 

it is just plain deadcode?

immediateByteSubclass: className instanceVariableNames: instvarNames classVariableNames: classVarNames package: package

"Added to allow for a simplified subclass creation experience. "

^ self

immediateSubclass: className

instanceVariableNames: instvarNames

classVariableNames: classVarNames

package: package

If that's of any help, I was able to track it back to Squeak 5.0 and it had no sender in that version too!  The author's initials are eem.

This one looks strange and seems indeed to be dead code. 

Maybe it was an attempt to make a specific class definition keyword for CompiledMethod / CompiledCode / CompiledBlock. Right now there is a specific case in the code somewhere to use the specific compiledCode layout for those 3 classes instead of the byte layout which is normally used for the keyword variableByteSubclass: that those 3 classes use.

I am not sure immediateByteSubclass: makes sense though. I would rather have compiledCodeSubclass, variablePointerAndByteSubclass or something like that.
