I guess I did not ask my question very clearly. Sorry about that.

What does the "#{ }" do for you? I think what I am missing is the feature provided by having that as a wrapper vs bare.

Does that make sense?
Thanks
Jim

You mean:
puts "#{a}"

Right? If so then it simply helps to do:

puts "foo=#{a} allows you to do more interesting things"

If you just want to print 'a' then there's no reason to do "#{a}" it
would be like doing "%s" % [a]; you can do it, but it doesn't make
sense.
