What is always missing for me in these lists is a tutorial for knocking together a small lambda calculus + dependently typed interpreter in C. Not ML, Not Ocaml, not, Haskell, not any language that has _already_ got lambdas in it!

Always when I read these I see, "get your Haskell compiler and..." and I'm like, if I knew Haskell well enough to do that I wouldn't be doing this tutorial in the first place.

Case in point, article says "particularly for programming pracitioners who didn’t learn it at school." -- Correct! I taught myself Basic, I taught myself a bit of x86 assembler, most importantly, I taught myself C. My working mental model of a computer is the C machine model. And even now, now that I know Ruby with its lambdas, I know that Ruby is written in C. And the Linux kernel. And Nginx (C++ maybe? Dunno). And on, and on.

Show me the tutorial where I can build, _in C_ a bare bones working (tail recursion) implementation of the lambda calculus with type inference and dependent (algebraic?) types and I'll shake your hand and call you a champion.

Closest I've seen is Make A Lisp - https://github.com/kanaka/mal but I don't think it has the sweet types and tail recursion and other good stuff. PS: bonus points if Regexen are native type :)

(Open to suggestions (I am))
