fragments and React

I keep finding that how different systems handle document fragments is a 
useful indicator of how they look at the world. React is a pretty 
popular framework from Facebook, one I mostly like except for odd things 
deriving from their particular mixture of markup and JavaScript.

They recently added more explicit fragment handling, and it might be 
worth your time to explore it:

https://reactjs.org/blog/2017/11/28/react-v16.2.0-fragment-support.html

Among other things, their requirement of key attributes (but no other 
attributes) in some contexts and their prohibition of attributes in 
other places suggest a more element-centric approach than I've seen in a 
while.  Attributes remain available through other syntactical 
approaches, but shortcut syntaxes tend to be a good indicator of how 
developers want their tools used.

Just another potentially fun aside!

Thanks,

Simon
