I'm looking forward to deleting all the annoying `.toJS()` conversions everywhere I've used an immutable-js collection rather than a js array. (PR: https://github.com/facebook/react/pull/2376)

Oh god, this. Using Immutable (via Immstruct) has been glorious, but this has been a minor annoyance that I'll be glad to be rid of.

Now all I need to do is sort out some issues with dispatch and I'm good to go...

Does Immstruct use Immutable's cursors? If so, you'll still need to use .toArray() when dealing with a cursor to an array. React doesn't like what you get after mapping over an IndexedCursor.

It does, but you can just .deref()

I'm usually looping over cursors I want to pass as a prop to a child component. Deref-ing there would sorta defeat the purpose of cursors.

Ah, fair enough. I usually deref before handing the data off to the rendering chain, on the basis that future updates will just kick off another render loop.
