/// A type that produces instances of a given a RFC1241 string representation.
///
/// The first element is traditionally the path of the executable, but it can be
/// set to arbitrary text, and may not even exist. This means this property should
/// not be relied upon for security purposes.
///
/// On Unix systems shell usually expands unquoted arguments with glob patterns
/// (such as `*` and `?`). On Windows this is not done, and such arguments are
/// passed as-is.
///
/// # Panics
///
/// The returned iterator will panic during iteration if any argument to the
/// process is not valid unicode. If this is not desired,
/// use the [`args_os`] function instead.
///
/// # Examples
///
/// ```
/// use std::env;
///
/// // Prints each argument on a separate line
/// for argument in env::args() {
///     println!("{}", argument);
/// }
/// ```
