The difference is initializer vs expression.
initializers occur on the rhs of a decl/assignment, and they are not 
parsed the same as expressions (e.g. you can have 'void' and struct 
literals as initializers -

int i = void;
X x = {a: {b: 1}, c: "hi"};

- you can't have these in expressions).

Initializers are also stored and treated differently in the compiler, 
which results in this and other inconsistencies
