This is the default way emacs has edited perl files for as long as I can
remember (back to 1996). It became my standard of editing perl files just
because of that. For everything else, I use tabs.

Probably because Joe probably uses vim ;-)

I rather have all tabs, or the tab and spaces. I find 8 spaces to be a
waste of memory and disk space.

My 1/2 only made it consistent, as the original code had the tab/spaces mix
and just a few lines that were modified by others broke it by adding all
spaces.

I'm guessing this is not strange to other perl developers who uses emacs.

I don't use it either. I was trying to make vim match emacs. Of course for
those that use something else, it wont help. I'm curious, what's your main
editor that you use?

OK.

I'm fine with that.
