One-line form for single definitions:

fluid_let!(static ENABLED: bool);

Multiple definitions with attributes and visibility modifiers are also supported:

fluid_let! {
    /// Length of `Debug` representation of hashes in characters.
    pub static HASH_LENGTH: usize;

    /// If set to true then passwords will be printed to logs.
    #[cfg(test)]
    static DUMP_PASSWORDS: bool;
}
