You're welcome! I think I first came across it when I was developing a
Facebook app: FBML tags have the form fb:something (that is, they're in
an XML namespace), and I didn't want to use a string for a content_tag
tag name if I could help it. Obviously, :fb:something doesn't work, but
:'fb:something' does.
You can use a double-quoted string too, and get the expected
substitution. Nice way of generating :"#{symbols}" on the fly.
