Using the function name as the identifier was an experiment which I 
think was a bad idea. I'll roll that code back out.

Before I started using the function name, I used an arbitrary 
identifier which was opaque and made debugging difficult. With the 
addition of the programmer-supplied identifier, debugging can be made 
easier by providing it, and an opaque identifier can be used if none is 
provided.
