On the Difficulty of Building a SETL Compiler From Scratch

I had my first — and hopefully not last — phone conversation yesterday with Guido von Rossum, the creator of Python.

I said during the call that I was going to write a SETL compiler from scratch, and that I hoped I to finish the project by the end of this summer.

Guido said he thought it would be a difficult project, and wished me well.

Guido, I’m done!

Python is a subset of SETL.

The Python compiler is the compiler of that subset.

Thus, the following script defines a compiler for the same subset of SETL:

/bin/sh
cp $1.stl $1.py
python $1
