I read about that, and my instant worry was about the whole world of tabs-vs-spaces. So-called "smart" editors might think that the indent in your example is best served by a tab and some spaces to 'hello', two tabs to 'there', and two tabs and some spaces to 'test'. What is the right amount to remove?
Since indentation is a visual thing but perl and emacs and vim and msdev.exe will likely not discuss their various rendering strategies, these indented here-docs are likely to get out of whack.
