Rewrite a URL segment into a parameter with JSON string encoding

[Taras Puchko]

Hello,

I'm trying to use a URL segment as a key for a view, like the following:
{
  "from": "/tags/:tagname",
  "to": "_view/by-tag",
  "query": {"key": ":tagname"}
}

The problem is that the key have to be JSON-encoded, which complicates my
API. Every client has to know how to JSON-encode strings.

However, I have found a workaround. If I use arrays for my keys the
following works:
{
  "from": "/tags/:tagname",
  "to": "_view/by-tag",
  "query": {"key": [":tagname"]}
}

I'm wondering if there is a more efficient solution for this problem.

Thanks,
Taras
