A preliminary C# expression for the Toyl model in Fig. 10.1 is now posted on github.
I rewrote this sucker about five times before I landed on the revision currently posted. What did I learn?
First, I found ways to use delegates to represent lambda expressions instead of creating separate classes for each one. That made the code a lot smaller and a lot tidier.
Second, in the case of currying and creating higher order functions, I found a way to define "delegate factories" that would generate the delegates I needed.
I'm actually pretty happy with the resulting code. In the next post, I will disassemble it and see what it looks like in CIL.
