Maybe I could expand a name into its full name and use that.
e.g.:
namespace bla { class myclass { void mymethod() { } } }
then the full name of mymethod would be bla::myclass::mymethod would be
unique enough to me (including filename).
Can I somehow get this out of it?

Always wondered what the latency of your webserver is? Or how much more
latency you get when you go through a proxy server/tor? The numbers
tell the tale and with HTTPing you know them!
