> Three idioms are common in modern languages but unavailable in Groovy:
> * Tail rest binding: {{def (h, *t) = list}} - separate the head from the remainder. Common in functional code (recursive list traversal, pipeline-style processing of streams and iterators).
> * Map-style destructuring: {{def (name: n, age: a) = person}} - extract named properties or map keys directly, without intermediate variables.
> * Rest in non-tail positions: {{def (*f, last) = list, def (l, *m, r) = list}} - useful when the boundaries are at the ends rather than the middle.
