The Importance of Interrelation in Crystal

There's been a wish to have a rapport in crystal, like read, evaluate, print, and loop. There has been a community project which kind of simulated that with like recompiling the program or inserting previous state into it. And you could get around to some degree for debugging with using just standard debugger like like GDB or something. But yeah, we on the verge of having an interrelated crystal, which is really awesome.
