Hi All,

Can somebody take a look at bug #9580? It's a C++ puzzle. Two as if equivalent 
expressions demonstrate different behavior. This one
    auto expr = (this->self("SOME_STATE") += someTokenDef);
calls boost::proto::detail::exprns_::operator +=.

However this
    auto lex_def = this->self("SOME_STATE");
    auto expr = (lex_def += someTokenDef);
calls boost::spirit::lex::detail::operator +=.

My guess is that it changes templates instantiaon order, but still I can't 
explain it and thus can't fix it.
