restore correct argument passing for Regexp.compile when encoding is
present but flags are not. regexp literals like /a/n should compile to
Regexp.compile("a", nil, "n") with 3 arguments, not
Regexp.compile("a", "n") with 2 arguments.
the bug was introduced during refactoring when the nil-insertion logic
for the options parameter was accidentally omitted. now properly inserts
OP_LOADNIL when flags are absent but encoding is present.

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
