That would not work if there were any parameters to the function. Also
all other information would need to be duplicated e.g. the return
type.

It depends what you consider 'easy'. Here is an implementation
https://gist.github.com/Danack/27254e80b56bf477fd1f

As I said in the RFC, it does a significant chunk of work in userland,
including an exciting use of debug_backtrace to get the calling scope.
I am not sure it is actually a complete implemenation. I got tired of
writing it, and decided that it would be better implemented in PHP
core.
