retrieving name of a function inside this function

Dear list members,


is it possible to retrieve the name of a function or the exact call to that function from the environment created "inside" this function? I wrote a function for debugging on a cluster that saves all the objects inside the whole stack of function environments and would also like to retrieve the names of the respective functions. Perhaps also a method to simply retrieve the name of a function inside this function could give me hints to the solution.

Thanks
Jannis
