Python is an amazing language for many reasons, but code prototyping via the interactive interpreter has crippled my development speed in languages that do not have a REPL.
I recently came across CERN’s CINT, a REPL for C/C++. Finally! I have come to dread coding in these languages, especially C++, but I’m now looking forward to my next big C/C++ project. If you’ve used CINT, drop me a line.
