Subject: Re: [go-nuts] Why can't convert []T to []T2 if T2 is a copy definition
of T?

There is none. It would be perfectly possible and reasonable to make this
possible, but it probably didn't seem worth the effort to introduce this
special case into the language which has such a limited use. If you can't live
without, you can always use unsafe to do it yourself (though, of course, that's
unsafe).
What effort needs to make to convert []Age into []int?

why the underlying types of []Age and []int are not the same.
The underlying type of an anonymous type []T is []T.
What are differences between memory layouts of []Age and []int?
