  • Compiling compression algorithms through programs
    • Compiler as f :: (program, compression algo) -> program'
  • Does collapsing towers of interpreters work for programming languages with much bigger architectural differences than the ones in the paper?
  • Abstract abstract interpretation
  • DDCG
  • Minecraft but it's all sending code to run on a shared VM
  • PL where every state change is persisted in a DB
  • SteamDrill (Quinn) but it's layered abstractions that you can expand (Python->C->asm) & custom events
