• Style: EXTRA (VAR, VAR, NOARG, NOARG).

• Stack: [...] → [..., value]. Get obj[key], delete it, and push the value with the object resolved by name and the key resolved by name.

• Cache: none; a VAR row survives lowering only for a name with no fast slot.

• Compiler form: Folded by the compress pipeline from VAR obj, VAR key, ITEM_TAKE. May lower to FAST_ITEM_FAST_TAKE.

• Implementation: koskari/lib/opcode/VAR_ITEM_VAR_TAKE.c
