People are curious about Deno and where it will go. Right now it is a new project, so we have more questions than answers. My pet question: Will there be a CLI-local debugger with a good UX like pry+byebug or ipdb? With the current chrome-based setup, it takes far more click-and-drag in js than in python and ruby to stick a `debugger;` in a function, run a single automated test which calls that function, and see how variables are defined.
