description prop

[cknitt]

In react-intl, FormattedMessage accepts an optional description prop. Also (see https://github.com/yahoo/react-intl/wiki/Components#message-descriptor),

type MessageDescriptor = {
    id: string,
    defaultMessage?: string,
    description?: string | object,
};

has the optional description field, too, and the defaultMessage seems to be optional as well.

In Reason, we currently have

type message = {
  .
  "id": string,
  "defaultMessage": string,
};

How would we model the two optional fields? I think we would need a makeMessage(Descriptor) function with two optional labeled parameters.

And how do we model the fact that description may be either string or object? [@bs.unwrap] (https://bucklescript.github.io/docs/en/function.html#trick-2-polymorphic-variant-bsunwrap)?

At the very beginning, I chose not to think about it b/c it seems a hard problem to solve w/o introducing a new type & component :)
