Support for column selection

Hi,

suppose I have the ruby code below
```
# puts 1
# puts 2
# puts 3
```
Note that the code is commented. I'd like to run this code without uncommenting the lines. I believe the easier way to do this would be by using "column select" (Alt+Shift+Drag) to select the code without the `# ` character and `Run Code`. Unfortunately, this procedure runs only the **first line of code** and ignores the subsequent ones.

Is there a better way to accomplish this? Could you add support for column-selected code?

Regards
