String interpolation in Ruby doesn't work?
Question
Recently I shifted to Ruby 2.0.0 from Ruby 1.9.3.
In 1.9.3 we were used to perform string interpolation using: 'http://#{get_host_name}.com , but since moving to 2.0.0, it seems to be not working.
Can anyone tell me if the syntax changed? How can I perform string interpolation in Ruby 2.0.0?

Regardless of which version of Ruby you're using, string interpolation doesn't happen in single-quoted strings. Use double-quoted strings or %Q -style strings.
