Yesss, let's do it. This syntax is a C relic only kept alive by 
the lack of viable alternatives. Named arguments functionality 
subsumes it completely, especially if it's usable with implicit 
struct constructors.

More downsides to {}:

- completely bypasses the constructor
- no way to disable default initialization of fields, making it 
silently broken if fields are added
- it's an expression whose validity is dependent on the type it's 
being assigned to, and those are always awkward with templated 
functions
   - hence there's no way to set its type without creating extra 
variables
- the syntax awkwardly clashes with object literals in dynamic 
languages, as well as hashmaps
