2008 Lecture Notes in Computer Science  
We report on our experiences with the Spy project, including implementation details and benchmark results. Spy is a re-implementation of the Squeak (i.e., Smalltalk-80) VM using the PyPy toolchain.  ...  Spy was built from scratch over the course of a week during a joint Squeak-PyPy Sprint in Bern last autumn.  ...  Acknowledgments We thank Orla Greevy for her careful review of a draft of this paper.  ...

Bridging the Gap between Machine and Language using First-Class Building Blocks

Evaluation The original Object Flow Analysis has been implemented by directly extending the Pharo VM. It required changes of a large amount of the VM code and took several weeks to implement.  ...  PyPy [123] follows a similar approach to the Squeak VM, although it is written in a more expressive subset of the Python language, called RPython.  ...
