Use existing parser generators and VMs instead of rolling your own

takeaway 3 connections

Halasz's pragmatic advice: you will almost never build a language toolchain by hand. Tools exist to generate lexers and parsers from a grammar, and mature virtual machines (YARV, the Java VM via JRuby, GraalVM via TruffleRuby, LLVM, Parrot, .NET) are ready to host Ruby-compatible languages.

Halasz's 'really bad news': you will never do this manually — tools exist.
