Paul King updated GROOVY-11964:
-------------------------------
Description:
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.
> Additional multi-assignment forms
