Search for property?

Is it possible to search for a specific property regardless of where it appears in the tree? Given a JSON document
```json
{
"foo": 1,
"a": {
"foo": 2,
"b": {
"foo": 3,
"bar": 4,
"baz": 5
}
}
}
```
I want to find all occurrences of property `foo` without a-priori knowledge of the document structure, yielding the same results as grepping the JSON data or using DOM querySelectorAll():
`["foo", "a.foo", "a.b.foo"]`
