Not related to the language switch, but I just want to say that I love Asciinema. Thanks to it I do small screencasts where normally I would be totally discouraged about the amount of work needed in order to really record a portion of the screen and upload a video recording. For people that want to show most of the times terminal based things (i.e. programmers), it is a zero-friction way to show an interactive session. Thanks for building it.
