inline record initialisation

[amitu]

For this record:

-- record person:
caption name:
integer age:
optional body bio:
optional mentor person:

We should be able to do this:

-- show-person:
person: John Smith, age=21

-- ftd.column show-person:
person person:

This is the "compact syntax". We will be very strict. Caption can not contain commas. Value in key value pairs can not commas or spaces.

The generalise syntax would be:

-- show-person:
person: John Smith
> age: 21
>
> The bio of John

You can also do this:

-- show-person:
person: John Smith, age=21
> mentor: Jane Doe, age=42

or,

-- show-person:
person: John Smith
> age: 21
> mentor: Jane Doe, age: 42
>>
>> Bio of Jane
>
> The bio of John

What If Caption Was Longer?

-- show-person:
person: John Smith Say This Is
>> A Long Caption
> age: 21
>
> The bio of John

Since on it's own a long caption using continuation:

-- some-component: This is a long
> caption, going on and on
some-other-key: even values can be
> long for that matter.

Think Not What Parser Can Parse, But What Would Confuse Humans

Even things that are technically parsable, we would chose not to parse, and raise error. We will optimise for what's crystal clear to human readers, and not for what all arcane stuff we can successfully parse.
