Simply use a separate temp variable
The dynamic_cast thing caused error: dynamic_cast from rvalue to reference type 'std::ostringstream &' (aka 'basic_ostringstream<char> &') with Clang in C++11 mode. Clearly putting the value of integer expressions into strings is a very esoteric corner case that very few C++ programs need to do, if it is this hard to do it and there is no obvious standard idiom that would work in all compilers and language vintages.
