Instead of taking binary string literals, take string ones instead, making it easier for users to define a module, i.e. instead of calling `module!` like: module! { ... name: b"rust_minimal", ... } now it is called as: module! { ... name: "rust_minimal", ... } Module names, aliases and license strings are restricted to ASCII only. However, the author and the description allows UTF-8. For simplicity (avoid parsing), escape sequences and raw string literals are not yet handled.
