Subject: [ruby-talk:21793] ANN: Fluid 1.2 (changing and restoring globals)

Inspired by the recent discussion of some of the trickiness involved in 
changing and restoring the IO globals, I extended my Fluid class to work 
with globals. You can now do this:

   Fluid.let(["$defout", File.open("logfile", "w"), :close]) {
     puts "This will go to 'logfile'."
   }
   puts "This will not."

Fluid knows the tricks required to handle $defout and $stderr. It also 
knows that you can't restore $stdin and $stdout back to the way they were, 
so it refuses to try.
