Type inference inside struct literals? Pretty Please?

[Nate Finch]

I wish go's type inference worked inside struct literals. Filling out config structs would be so much easier if this worked:

type Config struct {
  Runtime struct {
     Debug bool
  }
}
c := Config{
  Runtime: {
    Debug: true,
  },
}

^^ why can't this work?  It seems unambiguous.

The initial Config{ defines the type and tells the compiler exactly what everything inside it must be....

The reason that I wrote the struct that way is that it makes it very easy to read when the struct gets bigger. The sub-structs become basically just namespaces on the fields they encompass.  But if you then have to write a literal by redefining the struct, the literal becomes impossible to read

c := Config{
  Runtime: struct { Debug bool }{
    Debug: true,
  },
}
