Interesting middle ground between Swig+(C++)+$scripting_language and pure C++. A key weakness I see here is the lack of a standard library for Chaiscript. If I choose to use my preferred approach of Swig+(C++)+Tcl, I get a command line REPL shell and Tcl's excellent file I/O stuff, regex, string functions etc for free (the Tcl pieces I mentioned are never the efficiency bottlenecks in the sort of compute-intensive programs I write). I don't see enough here to convince me that it's better than pure C++ or swig+scripting language.
