I'm not sure what to make of this... I notice that the class side of
Object has protocol *Tools-Debugger contains method
#canonicalArgumentName, but class side of that package/tag does not
show #canonicalArgumentName, which instead appears under parent
"Tools".

Also btw, I notice package Tools-Debugger contain KeyPrinterMorph and
SyntaxErrorDebugger classes which seem to have no class references.

Not that every class needs to be referenced, but just floating this
observation in case someone knew if they need to be cleaned up or
moved.
