Converting Slice of Structs to Slice of Empty Interface

Assigning a slice of structs to a slice of empty interfaces is not straightforward due to type incompatibility, as seen in the following code:

type MyStruct struct {
    // ...
}

var src []*MyStruct
var dest []interface{}
dest = src  // Compilation error

This error arises because the compiler identifies the two types as incompatible. To resolve this, one must copy each element manually:

for _, s := range src {
    dest = append(dest, s)
}

Despite the tediousness of copying elements one by one, it is necessary because casting a struct to an interface involves wrapping the struct in an interface pointer and type descriptor. Copying each element separately ensures this wrapping process is performed correctly.
