Write Yourself a Haskell in Lisp (opens in new tab)

If you're interested in something similar but a little more theoretical, take a look at "Simply Easy"[1], a little paper on implementing a couple of variations on the lambda calculus. The main idea is to demonstrate how to evaluate a dependently typed language.

It starts by looking at how to evaluate the simply typed lambda calculus and then going from that to a dependently typed lambda calculus. Surprisingly, the transformation is not all that complicated!

The actual code is in Haskell.

Cool. Does it qualify as some sort of mutual recursion if you use haskell to build a lisp which builds haskell?

Hehe, I love this. I have been doing something similar, writing a compiler of Scheme-like language to x86 in Haskell.

The whole purpose of that mental gymnastics was to learn x86 assembly while practicing my Haskell ;)

Another 'X written in Y' post. Awesome.

I think I'll save myself the wasted time and just use X from the get-go.

Make the Yule-tide gay.
