112 generic struct nested

✓ Passing This code compiles and runs correctly.

Code

// TEST: Generic struct with two type parameters (Result pattern)
//
// ~struct(Result<T, E>) is a common pattern for error handling.
//
// Expected: Compiles and runs with Result<i32, []const u8>

~import "$std/types"

const std = @import("std");

~struct(Result<T, E>) { ok: ?T = null, err: ?E = null }
~type(IntResult = Result<i32, []const u8>)
