another vote for this - this is very useful with both defdelegates and other macros. (we use these extensively to define the accessible interface layer of our domain)

With defdelegate it helps to jump directly to implementation instead of to the defdelegate declaration.

In an ideal world there would be a single command that does both definition/implementation depending on context (if it's a defdelegate - jumps to implementation, otherwise jump to function definition).
