Getting member by name in runtime

[Marek Janukowicz]

I get a string from HTTP request and I need to process a member of this name 
of an object. I would like to use __traits(getMember) for that, but of 
course it doesn't work with runtime parameters. So what I ended up with is:

foreach( s; __traits(derivedMembers, typeof(obj))) {
  if (s == name) ...
}

Of course this looks suboptimal as I run the loop until I find a member 
matching the name. Is there any better way to do this?
