Document first level lists

[h2non]

Like in YAML, but use double dash -- to define nested lists at the first level of the document:

--
block: value
- list, of, elements
'string literal'

Other possible tokens would be:

• >> (overloading the operator)
• ::
• ->
• ^^

Could you please describe a real use case? I'm not very sure of understanding its intention.

[h2non]

Just take a look to this YAML example.

I want to introduce support to create first level arrays without using brackets

[h2non]

Link updated, sorry!

[aalda]

You mean an array of blocks?

[h2non]

that's it

[aalda]

What's wrong with expression?

[ 
  12, yes, 'cool'
  block: value
  [ John, age: 23 ]
]

It should coincide on the explained in issue #8. Either [] or -- or both.

[h2non]

List expressions explained in #8 only supports one dash -

Here is a representative use case

--
block: cool
yes # boolean
- 1, 2, 3
another block: yes

The above, compiled into JSON with the proposed double dash operator (--), will be:

[
  { "block": "cool" },
  true,
  [ 1, 2, 3 ],
  { "another block": true }
]

With this proposal, you can create first level arrays without wrapping it with brackets. I think this could be useful for common data structure use cases and provides a minor invasive sintax

[aalda]

I agree, but i think it should provide the two options for keeping it consistent.
