KOS_OP_ITEM_CONST_STORE

• Style: CONST (the key).

• Stack: [..., obj, value] → [...]. Set obj[key] = value with the object on the stack, the key a pool constant and the value on the stack.

• Cache: one KOS_CACHE_ITEM slot; the site elects a body for the container kind it first sees through the shared helper in eval/eval_item.c (see the items section of the VM reference).

• Compiler form: Shaped by compile/set-item when OBJ is a symbol or KEY is a feeder and a value is not, so the fold could not reach the named operands.

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