when running scripts via mruby -e or file, return values are unused. this adds a no_return_value flag to skip generating unnecessary code. for parallel assignment like a,b = 1,2: - before: 18 bytes, 5 registers, creates temporary array - after: 5 bytes, 3 registers, direct register assignment, no RETURN the flag is set only for the main program, not for libraries loaded with -r option. eval() and mirb continue returning values correctly.

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.
mrbcexecutable: A command-line tool for compiling.rbfiles into.mrbbytecode 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
