Hi Dan,

Eliot's original bootstrap is a bit tricky to use on other images than  
the ones he built it for (Croquet.1.0.18, Squeak3.9-final-7067 and  
Qwaq), because he's tweaking the compiler while it is being used to  
file in the code. While trying to adapt it for Cuis I broke my image  
too many times to count them!

I suggest using the sequence of changesets I prepared for Cuis. The  
idea is to prepare and test the new compiler without hooking it to the  
system yet, until it is good enough. Then, in one step, swap  
compilers, recompile everything, and only then remove the old compiler.

Although I believe I'm the only other person, besides Eliot, who  
successfully updated a different image to use Closures, my approach  
should be easy to adapt to any other image.

Get the Cuis update stream from  
https://github.com/jvuletich/Cuis/raw/master/PreviousUpdates/CuisUpdatesUpTo1511.zip . The relevant change set are 339 to  
392.

BTW, if possible, please keep up posted. It is always a pleasure to  
follow your work!

Cheers,
Juan Vuletich
