Subject: access to the case/when variable

Is there a way to access the variable being tossed through the
case/when structure?

case object.size.to_s
when /33/
  # ...
when /44/
  # ...
else
  abort "Invalid variable: " + ???
  # Is there a way to access the variable being tossed through
case/when?
  # something like:  $_, or $!
end

One can always do this:
x = object.size.to_s
case x
when /3ft/
when /4cm/
else
  abort "Bad match: #{x}"
end

But it would save a line to be able to access the actual variable being
used in the case/when structure.

Thanks
