I could encode functions by their name. I don't think that would scale 
to a large application with multiple developers, but it's not this kind 
of project anyway.
I'd be reluctant to accept that way if it means adding boilerplate code 
for every function that might ever be serialized. Since I'm planning to 
serialize an entire application, I fear that I'd need that boilerplate 
code for 90% of all functions, so even a single line of boilerplate 
might be too much.
