Steps to Reproduce and Observed Behavior

pub fn main() !void {
    var e: E = .foo;
    _ = &e;
    switch (e) {
        .bar => {},
        .foo => {},
        else => {},
    }
}

const E = enum(u8) {
    bar = 3,
    _,

    const foo: E = @enumFromInt(0xa);
};

test.zig:6:10: error: no field named 'foo' in enum 'test.E'
        .foo => {},
        ~^~~
test.zig:11:11: note: enum declared here
const E = enum(u8) {
          ^~~~

Expected Behavior

all test passed. with the following diff the test passes as initially expected since e is of type E:

-        .foo => {},
+        E.foo => {},
