Zig Version

0.10.0-dev.4213+91b05ad47

Steps to Reproduce

Compile test program with zig test name_resolution_error/file_1.zig.

Three files to reproduce:

name_resolution_error/imports.zig:

const file_0 = @import("./file_0.zig");
const file_1 = @import("./file_1.zig");

pub usingnamespace file_0;
pub usingnamespace file_1;

name_resolution_error/file_0.zig:

pub const A = struct {};

name_resolution_error/file_1.zig:

const imports = @import("./imports.zig");

const A = struct {};

test {
    _ = @as(imports.A, undefined);
}

Expected Behavior

Public A declared in file_0 is resolved unambiguously via imports namespace. As with stage 1:

$ zig test -fstage1 name_resolution_error/file_1.zig
All 1 tests passed.

Namespace name_resolution_error/imports.zig behaviour equivalent to:

const file_0 = @import("./file_0.zig");
const file_1 = @import("./file_1.zig");

pub const A = file_0.A;

Actual Behavior

As is, private A declared in file_1 exposed by imports:

$ zig test name_resolution_error/file_1.zig
name_resolution_error/file_1.zig:7:20: error: ambiguous reference
    _ = @as(imports.A, undefined);
