I was talking with my wife about this (who isn't technical at all, but
wanted to get her thoughts on terminology) and we came up with simply using
"within".

That is, we want the event to trigger if it is called "within" a function.
Hence, if you use:

  echo 'within=="$function_name"' > events/../filter

I think it's pretty obvious to what it means.
