• Identifying and explaining general concepts
  • scopes, bindings, environments
  • the background context behind 'running' a file/script/method
• Compiler stages:
  • how they're organized and how they're chained
  • how to define the first/last stages. Does the first stage have to be the parser? (I tried to implement a 'lexer' stage before then, and couldn't figure out how)
• Initializing the environment (things like initializing heap size/space) before compilation or execution
• A high-level overview of how code -> s-expressions -> AST/AST nodes -> bytecode
