google app engine - Converting slice of structs to slice of empty interface

Question

I'm trying to assign a slice of structs to a slice []interface{} (to pass into AppEngine's datastore.PutMulti. However, this is causing compilation errors as the two types are apparently incompatible:
cannot use type[]*MyStruct as type []interface { } in assignment

Basically I have:

var src []*MyStruct
var dest []interface{}
…
dest = src  // This line fails.

Is there anyway to copy src into dest without copying each element one-at-a-time?
