Proposal: Improve $$async$$ and $$done$$ api with promises

[thalesmello]

Every time the returned object is a promise, I propose we wait the promise to complete before fetching the result by default.

For example, instead of:

$$async$$ = true
var { promisify } = require('util')
var delay = promisify(setTimeout)

delay(1000)
  .then(() => $$svg$$ = "<svg><circle cx='30px' cy='30px' r='20px'/></svg>")
  .then(() => $$done$$())

We could have:

var { promisify } = require('util')
var delay = promisify(setTimeout)

delay(1000)
  .then(() => $$svg$$ = "<svg><circle cx='30px' cy='30px' r='20px'/></svg>")

The idea is that we would have it await by default.

What do you think?

I'm tracking this issue in the repository for the NEL package. See this issue.

I'm about to publish an update that implements display_data. I'll work on Promises in outputs next.

I'm closing this issue. Please, continue the discussion in the NEL issue.
