Subject: Iterating through the RE Group Variables (i.e., $1 thru $9)

I've written a quick and dirty regular expression tester, but there's one 
thing I'd like to try to clean up.

At the moment, to display all the groups, I have a series of print statements 
like:

print $1.to_s + "\n"
print $2.to_s + "\n"
...
print $9.to_s + "\n"

Surely there's a more Ruby'esque way, but I haven't found it so far.  I'd like 
to create a loop, or a range, or something and then iterate over it.  Here 
are snippets of some of the things I've tried, but I don't seem to be making 
any progress (and I'm shooting in the dark):

eval($#{i})

eval $#{i}

[1..9].each {|i| print $i.to_s + "\n"}

 [1..9].each {|i| print $#{i}.to_s + "\n"}

Is there a way to increment from $1 through $9 in some kind of loop?

Thanks!
