While are at it, it probably makes sense to add a note
about #instVarNamed: #instVarNamed:put:. These methods/messages
lend themselves to similar hacks.

Oh yes and as important as that and less noticed:
Its German translation is as good as the English original,
which is rarely the case for that sort of book.

In a nutshell:
It's Cuis with Modules.


Long story:

It consists of a Cuis patch
(https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse/environments/coreChanges)
and some packages that add environments and
environment local symbols to Cuis.
This part of the system provides the basis
for adding arbitrary environment/module
systems to Cuis. It also comes with
two simple environment implementations
that may serve as an example and are used to bootstrap
Haver's module system. (There is a Modules>#Modules module)
See: https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse/environments

The module implementation has
some superficial similarity with Python's modules.
Haver actually provides as simplified version of R6RS' module system.
I left out some esoteric features like prefixing imported symbols.
OTH I added named groups/sets of exported symbols I dubbed "interfaces".
Another difference to Scheme's module system is the fact
that exported symbols don't need to be read-only.
If you bind an exported symbol to a new value,
every importing module will see the change.
Discovering the implementation details is left to
the reader as an exercise :»]

I wanted a module system like those in common programming
languages like Python/Java/Module(2|3), while making still possible
to implement Environments as they exist (and being ignored
most of the time) in Squeak.

I the course of implementing the Module tools
(https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse/haver/modules)
I also implemented some UI/actions stuff to make thinks easier
for me:
https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse/haver/actions
https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse/haver/ui

There are also tools to repackage Cuis/Haver into a ZIP-file:
https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse/haver/packaging

Various experiments like:

In memory transactions:
https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse/haver/transactions

The beginning of an OODB/object-store:
https://hg.sr.ht/~cy-de-fect/HaverOnCuis/browse/haver/db

and other sundry stuff.

I also added themes, especially for syntax/highlighting
that makes reading code easier (for me).
Some hacks have the same purpose:

HTH and Best Regards,

Gerald
