The major reason I use neovim is because with the addition of :terminal command I no longer need to remember tmux commands and with the add-on neoterm I have a one button command to send the current selection (or line) to whatever terminal I please.

This means that when developing code in any language that has a REPL I can test it out as I develop line by line.

I've been looking for something like this in vim for a while (something like Emacs + ESS). I've found a few plugins and workarounds using tmux, but nothing as smooth as you said. I'll try it out.
