[Proposal] Use square brackets to specify an array index instead of assuming numbers as indexes

This would be great. Not only does it match how you would access an actual JS object (socialGraph.users[0]), but libs like Formik use this notation as well for its paths.

to add 2p., bracket notation could be used interchangeably and also, it could be used to escape dots in key names — if you pass a[0] you mean { a: [x] } but if you pass string, it means it's escaped object key name — a["b.c"] means {a: { "b.c": "x" }}

Numbers as indexes - that's the natural way of resolving array elements, i.e. natural because properties-numbers are treated as indexes directly, without any extra work.

Adding support for [] isn't just an extra parsing, but a heavy one, with most likely use of RegEx. As a result, it will be quite an impact on performance.

P.S. My tests showed this library is already quite slow as it is.
