[Cuis] Xtreams , Ometa and related

[Edgar J. De Cleene]

Your info is very useful.
The experiment until now is I can load OMeta in Squeak 4.6 from SqueakSource.
In my fork wich is Cuis 3,2 can’t load and several tricks for having the classes ordered before OMeta uses each failed.
So if you have the original .st of Alessandro , wish have it for try.
In Cuis as cloned from Github the preload package loads fine and the examples works as in Squeak 4.6.
I send mail here with link to .jpg picture.
But post load fails.
