title: Ada support for variables in put_line's?
body: <p>Does Ada have support for something similar to an Obj-C variable in a string?</p>
  
  <p><code>NSLog(@"This is text, here's a variable %f", floatvar);</code></p>
  
  <p>I'd like to be writing nice one-liners, like:<br>
  <code>put_line("The answer is %v", answer);</code></p>
  
  <p>instead of   </p>
  
  <p><code>put_line("The answer is ");<br>
   put(answer);</code></p>
