Subject: Iterators and blocks question

I am new to ruby and am trying to learn my way around it.  I saw the
following example somewhere on the net to read a file line by line and
list it to the console:

IO.foreach("test.txt") {|line| puts line}

This works great.  However, I am trying to take the next step(s).  For
starters, I would like to modify the above code such that it lets me
prepend the line numbers to each line as it is listed to the console.
Something similar to the listing below for example:

1.  First line from the file..
2.  Second line from the file...
..
..
12. Last line from the file.

What is the Ruby idiom for doing this?  Using the iterator and the code
block?

Thanks in advance.
Regards,

Bharat
