Subject: Return from a block?

I've had a couple of places where I really needed to just return from
a block.  From what I can see, if my block is inside a method, the 
return will return from the method, not return control *to* the
method.  I've ended up writing some very Pascal like code:

Find.find(*ARGV) do |f|
  
  if f =~ /[CVS|SVN]/ 
    Find.prune
  else
    $matches += 1 if match?(f)
  end
end

Where what I'd prefer to write would be:

Find.find(*ARGV) do |f|
  
  if f =~ /[CVS|SVN]/ 
    Find.prune
    return-from-block-to-method
  end
    
  $matches += 1 if match?(f)
end


Is there a way to return control from the block to the method?
