Type Alias ModuleFn 

pub type ModuleFn = Arc<dyn for<'ctx> Fn(&[ValueWord], &ModuleContext<'ctx>) -> Result<ValueWord, String> + Send + Sync>;

A module function callable from Shape (synchronous).

Takes a slice of ValueWord arguments plus a ModuleContext that provides access to the type schema registry and a callable invoker. The function must be Send + Sync for thread safety.
