static initialization of structs

[Dan]

In the thread on compiling DSSS and build tools someone mentioned 
a format for initializing environment data of a struct:

  Environment env = {
       tests: true,
       verbose: true,
       importDirs: ["../deimos"]
  }
A followup comment says "isn't that syntax intended to be 
deprecated?"

Is this accurate - that the nice json-esque syntax for 
initializing structs will be deprecated? If so, can someone give 
color on why/when?

Also, for this and other issues regarding features going away, is 
there a central place where these items are being tracked? How 
can we know what is on the chopping block?

Thanks
Dan
