I think a Go REPL would be a very cool project. I think it is doable. I always have ipython up, when I program in Python.

There is even a C++ REPL somewhere. It basically compiles very time your enter the expression and runs the code. I think it can be done in Go (but someone correct me, if I am wrong here).

You can try this: https://github.com/vito/go-repl

I use https://github.com/shurcooL/goe, which is a repl without the loop.

go run is surprisingly effective for playing around with code. I keep a main.go file in my home directory that I edit with vim and then run with ':!go run %'. Go compiles and runs fast enough that I almost don't notice its'a compiled language.

There is also the Go Playground[1], which is great for testing out and/or sharing small code blobs.
