Yukihiro "Matz" Matsumoto b287c12e48 mruby-compiler: raise error for pin operator with undefined variable

CRuby raises SyntaxError for `^a` in pattern matching when `a` is
not a local variable. Previously mruby silently generated an
unconditional fail jump, which also led to bytecode corruption
when combined with alternation patterns.

mruby-compiler

This mrbgem provides the mruby compiler, which is responsible for parsing Ruby code and generating mruby bytecode.

Functionality

The mruby-compiler gem includes the following components:

Parser: Translates Ruby source code into an abstract syntax tree (AST).
Code Generator: Traverses the AST to produce executable mruby bytecode.
mrbc executable: A command-line tool for compiling .rb files into .mrb bytecode files.

Usage

The mrbc (mruby-bin-mrbc) executable will generate compiled binary from Ruby programs via this gem.

Example of using mrbc:

# Compile a Ruby script to bytecode
bin/mrbc my_script.rb

# Run the compiled script
bin/mruby my_script.mrb
