Subject: passing function into another function

Hi,

I couldn't work out the syntax for the following:

class Reports
  def self.This; end
  def self.That; end
end

def do_something_with_a_report report
   # calls Reports::This or Reports::That, dtermined by what report is
   # something like report.call ?
end

I want to do something like:

do_something_with_a_report Reports::This

But that calls Reports::This and sends that value to the
do_something_with_a_report function.

In other words, I want to do something like passing a function pointer
to a function in C.
