Support for circular references?

[cressie176]

Hello. Thank you for writing these modules, I was previously using dot-path, but am unable to since it moved to ESM.

One thing I've noticed about get-value is that it doesn't support circular references. The following two examples result in undefined

const get = require('get-value')
const a = {};
a.b = a;
get(a, 'a.b'); // undefined

const get = require('get-value')
const a = { c: 1 };
a.b = a;
get(a, 'a.b.c')  // undefined

Was this intentional?
