digitalmars.D.learn - How to split strings into AA using phobos

A typical example would be to split the HTTP query string into an 
AA.

vibe.d has req.queryString, but no convenient wrapper to access 
it as an AA.

http://localhost/hello?name=abc&id=123

I've got this far.

         auto arr = req.queryString.splitter('&').map!(a => 
a.splitter('='));

Thanks

req.queryString[req.queryString.indexOf('?') + 1 .. $]
   .splitter('&')
   .map!(a => a.splitter('='))
   .map!(a => tuple(a.front, a.back))
   .assocArray

I am not 100% sure but I think query parameters names can occur 
multiple times in query string.
Therefore you need an associative array with string as key and 
string[] array as value.

By using associative array you loose the order of the parameters. 
Whether this is important for query parameters I do not know.

Kind regards
