Yes, this seems to do it for file/line/method

That seems to contain the solution for the function name.

And this is the right documentation, but I could not find (within
Object and Kernel) the construct I'm looking for (accessing calling
Module or Object).

#ruby 1.9
class Person
  def initialize(name)
    @name = name
    @where = self.invoked_from # returns Object
  end
  def report
    print "\n", @name, " instantiated in: ", @where, "\n"
  end
end

p = Person.new("Nancy")
p.report #=> Nancy instantiated in: main

Is there something like "self.invocation_from", or how could this be
implemented?

Note that this should work on object model, returning a "living"
object.
