reflect and iterating over the elements in a struct

[Johann Höchtl]

I figured out I can iterate through the fields of a struct in this Goplay:

http://play.golang.org/p/NJXaPCJbvB

However I wonder why reflect.FieldByIndex takes a slice instead of a plain integer,
or  I missed a better way iterating over the struct fields. E.g. I expected to see a []Value slice at some point.

You seem to be looking for the Field(int) method, which takes a plain integer.
FieldByIndex([]int{1,2,3}) is meant to access x.Blah.Foo.Bar where
Blah, Foo, Bar are the 1st, 2nd, 3rd fields of their structs.

Oh my, now it's obvious.

Powerful abstraction.
