As far as methods go there's remove_method and undef_method. For
constants theres remove_const. An idea I've had was to fork, although
that's a little heavy handed

eg:

... code ...
pid = fork do
   require 'this_will_go_away'
   but_so_will_this_var = ThisWillGoAway.new
   but_so_will_this_var.do_something
end

Process.wait pid

p but_so_will_this_var # NameError
