Modifying the parser and AST to incorporate Defining and implementing the small-step substitution-model semantics of a The "environment model" differs from the "substitution model" by lazily recording substitutions in a map Textbook: ... Implementing an environment-model big-step interpreter for a Defining and implementing the big-step substitution-model semantics of a A "closure" is a data structure containing the code for a function, as well as the environment that "closes" off its free variables.
Defining the small-step semantics of `let` expressions, based on substitution Textbook: Compilers translate code from one language to another. Interpreters execute code. Virtual machines and just-in-time compilation ... A comparison of big-step vs. small-step semantics, and substitution model vs. environment model Textbook: ... Achieving polymorphism for `let` expressions in HM The semantics of `let` uses a notion of substitution, but, how should that be defined? These examples lend intuition. Textbook: ... An example of how environment-model evaluation works. Substitution-model evaluation is list-like; environment-model, tree-like.
In this tutorial, I will show the basic ideas of recursive functions, lambdas, and how
