Sorry, guys, This is the first feature that I am writing in this Ruby issue tracking system, and If I make any mistake, please understand :).

Today I was going through this language, i.e. V language (mainly their website) and found its basic code like below,

```ruby
fn main() {
	areas := ['game', 'web', 'tools', 'science', 'systems',
	          'embedded', 'GUI', 'mobile'] 
	for area in areas {
		println('Hello, $area developers!')
	}
}
```

I like this kind of string interpolation which looks so simple to write. If we try to write the same code in Ruby, we need to write like this,

```ruby
areas = ['game', 'web', 'science', 'system']

areas.each do |area|
  puts "Hello, #{area} developers!"
end
```

Instead of using `#{area}` syntax for string interpolation, can we have something like `$area`? This might save some keystrokes. 

I know that Ruby has already occupied this `$` character. But we can use another character which is not used in Ruby.

We can close this feature request if we already discussed on such topic before.
