Is there a scripting language for C++ (like perl) which can be used for rapid development and use some tool which can convert into C/C++ program to get higher performance f
Many projects combine e.g. C++ and Python -- see for example boost.python.
I prefer R and use the Rcpp interface from R to C++.
Either case gives you your scripting language for prototyping and easy 'glue' to C++ for performance.
