BC evaluator implemented in OCAML

How to run

dune runtest

Features of this implementation

• scopes are created per function call
• arguments and variable are assigned within their scope
• arguments and variables are accessed by recursively checking each scope defined in the entire programs environment starting with the local scope
• recursive functions
• special statements (break, continue and return) throw an exception when evaluated
• these exceptions are caught when evaluating statements nested within other, certain statements (for, while...) and are meant to halt execution of code in some manner within the statement but preserve the state of the environment.
• function calls catch return e exceptions and evaluates the expression e
• while and for loops catch break and continue exceptions
  • break will exit the loop
  • continue will skip all subsequent statements within the loop and start to evaluate the condition of the next loop
