xload, at the moment, does not detect any collisions when working with nested structs that are reused.
Example
```go
type A struct {
B D `env:",prefix=D_"`
C D `env:",prefix=D_"`
}
type D struct {
S string `env:"S"`
}
```
When a loader returns `"D_S: "value"`, both `A.B.S` and `A.C.S` are assigned value "value", without any warning, potentially introducing uncaught behaviour exceptions.
Proposal
Add some mechanism to detect collisions in the overall state of a Load call on the root struct.
