For RuntimeScalarReadOnly (immutable scalars), lvalue is null. When NonStrict methods are called, we now delegate to super instead of calling vivify(), which allows symbolic references to work without trying to modify read-only values. Result: magic.t now passes 158/208 tests (was crashing at 103) Known issue: Double symbolic dereference like ${"foo"}{key} still returns empty.
