rad was rewritten in Nim, reasons include:

• more readable
• less LOC; even when more features have been added
• more productive; faster to implement new features compared to Rust
• lower system resource usage; one third of what Rust uses
• smaller executable size; one tenth (300 KB) compared to Rust (3 MB)
• can be built using existing toolchain because Nim transpiles to C; Rust is harder to bootstrap
• parsing packages is slightly faster
