…edClosures/flag off by default (GEP-27 S1)
Add closure packing on top of the SAM-lambda hoisting: an eligible closure
literal's body is hoisted into a synthetic method on the enclosing class and
the literal is replaced by a shared PackedClosure adapter, removing the
per-closure generated class (and the nested $_closure1$_closure2 name
explosion) while the value stays a real groovy.lang.Closure.
Capability analysis (PackStrategy, ClosureWriter.chooseStrategy):
- a single decision point selects FULL_CLASS (S0) vs PACKED_ADAPTER (S1);
- triggered by the @PackedClosures annotation (trust path, dynamic or
static), or automatically under @CompileStatic when the type checker PROVES the
closure delegate-independent
> hoist eligible closure bodies to a shared adapter @PackedClosures/flag
