Parser Hacking [09]: Parsing Method Calls vs Local Variables | Unique Ruby Parser Feature
Ruby's parser has a unique feature: it keeps track of local variables defined in the current scope so it can determine if an identifier is a method call vs a local variable lookup. Let's teach our parser to store local variable assignment in a vector so we can mimic this behavior!
About the Project: Natalie is a very early-stage work-in-progress Ruby implementation that compiles Ruby to an executable. It does so by transpiling Ruby to C++ and feeding it to gcc or clang to produce a binary.

Continuing our series on building a Ruby parser with a Parsing Expression Grammar, this time we tackle a few minor housekeeping items and then teach out parser to parse more than one expression, i.e. a program. :-)
