Inline object notation

[1ec5]

The readme says this library doesn’t have a way to represent JSON object literals for the literal expression, due to a jsep limitation. Perhaps there could be an inline notation such as object(key1, value1, key2, value2, …).

There are a few error conditions to consider:

• Duplicate keys
• An odd number of arguments to the function
• Keys that aren’t strings

Besides literal, an object literal syntax is needed because mapbox/mapbox-gl-js#6270 introduced a Collator object type that can be passed into various comparison expressions.

Looks like there's a (rather old) PR adding object literal support: EricSmekens/jsep#14

The number-format operator introduced in mapbox/mapbox-gl-js#7626 also takes an options object as an argument.
