@ottobackwards this looks good to me now. I re-built everything, ran the
tests, and played around in stellar shell. The only question I'm still not sure
about is the one that deals with backwards compatibility. I *believe* with the
new keywords (`default`, `match`) we can potentially break expressions with
this change. @ottobackwards and @cestella do you have an opinion on this?---
