// Interning a large (~64KB) array type and using `{}` formatting elsewhere must
// NOT scalarize into an O(N) SelectionDAG (which crashed `sx build` / made
// `sx run` take ~12s). The array Any-unbox formats via a SLICE VIEW of its
// storage — no whole-array load.
//
// Regression (issue 0125): `any_to_string`'s `case array:` arm used to do
// `array_to_string(cast(type) val)`, loading the whole [65536]u8 by value and
// reading each element off the loaded aggregate. Now the dispatcher builds a
// `{ptr,len}` slice view of the payload pointer and formats that — output is
// identical (`[a, b, c]`), and a large unrelated array type costs nothing.
