//! Declarative `return Err(...)` shorthands for the repetitive `bail_*`
//! patterns across the crate. Each macro expands to the equivalent
//! `return Err(Variant(...))` so it can be used inside any function
//! whose error type matches.
//!
//! Naming: `bail_<variant>_<type-shortcode>!`. Type shortcodes:
//!   estim   → EstimationError
//!   basis   → BasisError
//!   gamlss  → GamlssError
//!   tnorm   → TransformationNormalError
//!   surv    → SurvivalError
//!   sls     → SurvivalLocationScaleError
//!   custom  → CustomFamilyError
