That's not going to work very well with D. You tend to get far too many levels 
of indentation for that to fly. With static if (and potentiall multiple layers 
of static if), classes, templates, etc. all on top of the normal if statements 
and while loops and the like, and it can very quickly reach 3 - 4 indentation 
levels on simple code, let alone what more complex code has. It's that much 
worse when you use much in the way of functional-style programming and chain 
function calls, since then not are the lines indented a fair ways, but they 
tend to get long. I suspect that you'll find 8 character tabs and 80 character 
columns to be a frustrating combination, but you can do whatever you want.

Phobos uses 4 character tabs with a soft limit of 80 characters (on average, a 
line should fit within 80 characters, but it doesn't have to) and a hard limit 
of 120 characters (a line should _never_ exceed 120 characters). And that 
seems to be working fairly well for us.
