/// 🧉 » create string
/// --
///
/// create a new `String` from a string literal or a string expression -
/// this macro is equivalent to `String::from(<args>)`.
///
/// ### Example
/// ```rust
/// use lool::s;
/// let s: String = s!("hello world");
/// ```
#[macro_export]

    ($s:expr) => {

/// 🧉 » fail macro
/// --
///
/// this macro is equivalent to `Err(eyre!(<args>))`.
///
/// same as `bail!` but without the explicit return
///
/// ### Example
///
/// ```should_panic
/// use lool::fail;
/// use eyre::Result;
/// # use eyre::{set_hook, DefaultHandler};
/// # fn setup_eyre() {
/// #    let _ = set_hook(Box::new(DefaultHandler::default_with));

/// fn main() -> Result<()> {
///     # setup_eyre();
///     fail!("permission denied")
/// }
