qs: support hierarchical QUERY?

[yorkie]

Even though the RFC3986 told us the QUERY should be non-hierarchical, but some libraries supported the following QUERY schema:

foo[x]=foo.x&bar[y]=bar.y

Such that how about supporting from the core module?

I'd say let userland do it.. The qs module does this, I think?

Okay, if any collaborators think this should be done at user-land, feel free to close this, thanks

I would strongly recommend against this in core. There is no standard and the behaviour differs a lot between back-end systems. Better to just use qs if you really need this.
