Introduction
------------

SOM is a minimal Smalltalk dialect used to teach VM construction at the [Hasso
Plattner Institute][SOM]. It was originally built at the University of Århus
(Denmark) where it was used for teaching and as the foundation for [Resilient
Smalltalk][RS].

In addition to PySOM, other implementations exist for Java (SOM, TruffleSOM),
C (CSOM), C++ (SOM++), and Squeak/Pharo Smalltalk (AweSOM).

A simple Hello World looks like:

```Smalltalk
Hello = (
  run = (
    'Hello World!' println.
  )
)
```

This repository contains a RPython-based implementation of SOM, including

SOM's standard library and a number of examples. Please see the [main project
