This case can be considered a Category B source incompatible change as per 
https://quips-qt-io.herokuapp.com/quip-0006.html, because it clearly 
introduces ambiguity.

But {} is particularly special, so I don't know how we'd deal with it. I don't 
think this has come up for us yet. For one, the mailing list thread linked in 
the QUIP didn't address it.
