--- Comment #11 from Martin Nowak <c...@dawg.eu> ---
Slight variation of the bug where the aliased string is an lvalue, but cannot
be assigned.

cat > bug.d << CODE
struct InternedString
{
    void opAssign(InternedString other)
    {
        this.data = other.data;
    }

    string data;
    alias data this;
}

auto bug(InternedString s)
{
    import std.file : exists;
    return exists(s);
}
CODE

This breaks b/c some code in utf.d tries to `r = r[1 .. $]` slice an
InternedString.
