// Companion module for issue-0057 regression. The bug: an `xx <int>` argument
// to a variadic `format` (a comptime `..$args` pack), inside a function that
// lives in an IMPORTED module, was mis-typed as the enclosing fn's
// `target_type` (here `string`) instead of auto-boxing to `Any` — so it
// monomorphized `__pack_string` and ABI-coerced the 4-byte int as a 16-byte
// string fat pointer, corrupting memory at runtime. Fixed by clearing
// `target_type` while lowering pack args.

#import "modules/std.sx";
