Hey - I am Luca Casonato, Deno's new delegate at TC39. I am happy to answer any questions you all might have :-)
What are your thoughts on the do expressions proposal? Cause I think they'd be awesome for cleaner scoping of temporary variables.
I think they are great! Especially in combination with pattern matching (https://github.com/tc39/proposal-pattern-matching), or when using JSX.
