It is a good thing that cppfront lets you do that, then! Cppfront generates #line pragmas which tell the generated .cpp file which source lines to "blame" for each piece of generated code. This isn't something new and fancy for cppfront, it's a bog-standard pragma that your debugger already understands. So it will work the exact same as your current debugging workflow even if you mix cpp and cpp2 source files.
