Rails spinoffs - Feb 2006 - prototype.js Array.prototype.shift() method

I noticed that prototype.js defines a shift() method for the Array prototype.  
The base prototype already defines this method, is there a reason it is being 
redefined in prototype?  Maybe certain browsers aren''t implementing the
shift() method?  If that''s the case, shouldn''t there also be
an unshift()? :)

Thanks!
