Formatting using %#v loses the concrete type of any value (at least of basic types) that
is held through an interface type, which makes them impossible to reconstruct, and also
violates the claim of "a Go-syntax representation of the value", because the
result is a different value of a different type.

What steps will reproduce the problem?
http://play.golang.org/p/RebBqTAjS0

What is the expected output?
`main.Bar{Qux:main.Foo(0)}`

What do you see instead?
`main.Bar{Qux:0}`
