Returning the name of a caller function?

Hi all,

I'm sure there is a way to do this (perhaps with FunctionInfo), but I cannot figure it out yet. I would like to determine the name of a function that calls another function.

Example code below: if call "foo()" I should see "foo" printed to the history window, and if I call "bar()" I should see "bar" on the history window.

function foo()
  ///do stuff
  subfunction()
end
 
function bar()
  ///do other stuff
  subfunction()
end
 
 
function subfunction()
 
   print whocalledme() ////<---what should this code be?
   
end
