  for **sub warn**.
  
  ```raku
  multi warn(*@message)
  ```
  
  Throws a resumable warning exception, which is considered a control exception, and hence is invisible to most normal exception handlers. The outermost control handler will print the warning to `$*ERR`. After printing the warning, the exception is resumed where it was thrown. To override this behavior, catch the exception in a `CONTROL` block. A `quietly {...}` block is the opposite of a `try {...}` block in that it will suppress any warnings but pass fatal exceptions through.
  
  To simply print to `$*ERR`, please use `note` instead. `warn` should be reserved for use in threatening situations when you don't quite want to throw an exception.
  
  ```raku
  warn "Warning message";
  ```
