Reduced test that compiles with -preview=dip1000, but not dip1021.

@property deleteme()
{
    char[] cache;
    buildPath(cache);
}

char[] buildPath(char[][])
{
    struct ByCodeUnitImpl
    {
        auto opIndex(size_t ) { }
    }
    assert(isRandomAccessRange!ByCodeUnitImpl);
    return [];
}

char[] buildPath(C)(C[][] paths...)
{
    return buildPath(paths);
}

enum isRandomAccessRange(R) = is(typeof(lvalueOf!R[1]));

ref T lvalueOf(T)();
