Remove useless outer switch statement and convert nested if-else chain to a clean switch statement on node types. This improves code readability and maintainability in the parser's block handling logic. Key improvements: - Replace outer switch with simple early return for non-NODE_VARIABLE cases - Convert if-else if chain to proper switch statement on var_type - Standardize null checks to use != NULL consistently - Use break statements consistently instead of mixing return and break - Maintain exact same functionality while improving code structure The refactoring eliminates unnecessary nesting and makes the function's logic flow more explicit by directly switching on the actual node type rather than wrapping it in a redundant switch statement.

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
