I would like to second BrowserUK's suggestion to use a hash.

Also to point out that symbolic references are generally a (very) bad idea and point out this article by the Dominus, detailing how and this one detailing what to do instead and why and finally this one to drive the final nail into the symbolic reference coffin.

I hope this helps Ralph in his quest for The Truth (tm).
