It is great that you are fixing this... it always seemed a little sad 
to have such a broken example in the system.

I hadn't noticed that the mirror primitives worked with special 
annotation objects instead of strings.

This seems to work:

 ((reflect: shell) _MirrorCopyAnnotation: 'Comment: hello') reflectee

I couldn't find the actual annotation parsing code in a quick look 
through the VM. My initial impression is that the strings for nested 
annotations are simply concatenated (with the proper separator, of 
course), but it would be interesting to do some experiments to confirm 
this.

Are you aware of the Mango parser generator? Mario used it to generate 
the parser for Smalltalk and I wrote most of a Self grammar for it (I 
am not sure it is possible to finish it, however, and I have mentioned 
this a few times on this list already):
