Go slices package — Modern Helpers
`slices` (Go 1.21+) ships the iteration helpers everyone wrote by hand for years: Contains, Index, Sort, SortFunc, BinarySearch, Clone, Reverse, Equal, Max/Min.
Python argparse with Subcommands
Standard-library CLI framework. Subcommands (like `git COMMAND`) require a sub-parser per command, each with its own arguments and handler.
Go maps package — Modern Helpers
`maps` (Go 1.21+) adds Keys, Values, Equal, Clone, Copy — replaces the slice-of-keys boilerplate you used to write to iterate a map deterministically.
Python Stdlib .env Loader (no dependency)
Parse a `.env` file into a dict and optionally export to os.environ. Skips comments and blank lines, strips surrounding quotes — no python-dotenv dependency needed.
