Hello @zenspider, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

Summary of Changes

Hello! Gemini here, providing a summary of this pull request.

This PR aims to fix issues related to string mutability in the build process when Ruby's frozen-string-literal is enabled. Specifically, it addresses cases where string concatenation or modification is attempted on string literals that are frozen by default under this setting. The changes ensure that necessary strings are mutable by creating mutable copies using the unary + operator.

Highlights

Frozen String Literals: The core issue addressed is the behavior of string literals when frozen-string-literal is enabled, which makes them immutable by default.
String Mutability Fix: The fix involves using the unary + operator (+'') on empty string initializations where subsequent concatenation or modification is expected. This creates a mutable copy of the frozen string literal.
Build Process Compatibility: The changes are specifically targeted at the build process Rake tasks to ensure they function correctly even when Ruby is run with --enable-frozen-string-literal.

Changelog

tasks/mrbgems.rake
- Ensured string variables gem_func_decls, gem_funcs, and active_gems are initialized as mutable strings using +'' to allow for subsequent concatenation when frozen-string-literal is enabled.
