So here it is:

class QueryString {

  const string __qstr;
  QueryString() {
   throw Exception("Invalid constructor"); // defined in Exception.h

  QueryString(const char* s) : __qstr(s) {}
  QueryString(const string& s): __qstr(s) {}
  http_map* parse();


PS: The default constructor is pretty dumb logic, I'll be changing that :)

This doesn't compile on my box, saying `undefined reference to 
QueryString::QueryString()' or any other constructor.

It doesn't matter if I define it inside (therefore implicitly inline as 
per ANSI) or outside using the inline keyword, it still won't compile 
(at least on my arch64).
