You might consider sorting the keys too. The minor slowdown may someday pay off in the regex optimizer. Of course I took the Regex book to work Monday so I don't have it here. It said something about refactoring similar words and order dependencies in alternations...

Other than s///go as mentioned already, I don't see anything else you can do with this. I'd have to throw Benchmark at alternatives since this is pretty sexy code =)
