Trying to write one function that will find a
full row or column in a 2D array (for tic-tac-toe).
Like this:

------------------------------------------
$grid =
   [[' ',' ','O'],
    ['X','X','X'],
    ['O',' ',' ']]

def doAxis (outr,inr)
  outerLoop:
   [0,1,2].each do |:"#{outr}"|
     [0,1,2].each do |:"#{inr}"|
       if ($grid[row][col] != 'X')
       next outerLoop # is this supported?
       end
     end
     puts "Got 3 in a row!"
     return true
   end
   false
end

doAxis 'row', 'col' # want to find full rows
doAxis 'col', 'row' # want to find full columns
-----------------------------------------------

Is this possible?  So far Ruby doesn't seem to like it.
What are the limits to how you can use this construction?

:"#{foo}"
