Adding small REPL for development purpose

I am trying to read and understand ChakraCore architecture. In process of doing that, when I want to change or fix small part of ChakraCore runtime, I have to run tests or something, which is unnecessary for most of the time.

I am developing small REPL inside of ChakraCore project which could be helpful to many people (I think) so every time I am trying something new or messing with something I can run and test it simply inside Visual Studio without going through all the pain of testing and other stuff. It is for my own usage right now, but we can work on it to make it something better and ultimately adding it to main repo.

What is your opinion to add small REPL like subproject (or it could be "-repl" flag for ch.exe) ?
