      Was thinking last night: what would a version of async/await look like that I'd actually want to use. If only it'd been closer to this.pic.twitter.com/sh0EQHiut6

      await just adds an errback to the end of the function

      IMO errors should implicitly bubble up & crash unless handled explicitly. Seen so much broken code because of missing error propagation.

      haha, yeah def for servers. Kinda come around on this for browsers - but think forcing it from language semantics was def not the right move

      const wrap = fn => asde(util.promisify(fn)) const [err, res] = await wrap(fn)('foo') This should work already :) and yeah wrapping but...

      Actually no, you only need the asde library https://www.npmjs.com/package/asde  (by @0x00A )

      I'm curious, what don't you like about try/catch blocks? Just the indentation?

      Replying to @timwis @juliangruber and

      The fact that it isn’t concatenable, because it’s not an expression. It forces you to use non-constant variables.

      Replying to @seidtgeist @evilhackerdude and

      Do you mean because const is block-scoped so using it inside of try restricts access to that block? And what do you mean by concatenable?

      Yeah, the indentation is what kills it for me. Also the vast majority of async/await examples leave out err handling somehow :/

          Exactly. Would be cool if I could do: const v = try await fn catch NaN lol

          i don't mind the indentation personally, most errors can be bubbled up in my projects
