how to handle object keys beginning with a number

Ah, nope not expected. If a key is only a number, it will be parsed as a member of a sparse array. If it only contains a number, it should be getting parsed as an object key, so that's where this bug exists.

Note that you can override the creation of an array at all by passing { arrayLimit: 0 } to the second parameter of Qs.parse

Qs.parse('a%5B12+v%5D=c', { arrayLimit: 0 });
{ a: { '12 v': 'c' } }
