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.
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.
