I don't think there is the best coding style (personally I like both K&R 
and Allman styles). IMHO things are different with indention. Why does 
Phobos use 4-space indentation?

The following article (IMHO) completely covers tabs vs spaces problem:
http://www.emacswiki.org/cgi-bin/wiki/TabsAreEvil

It shows that tabs (in spite of the article title) are really good and 
should be used always (and only) for indention. Looks like Allman style 
doesn't prevent this (if it does, what is the reason?). So:
* Such tab using shows respect to a programmer allowing him to configure 
tab size as he prefer.
* Sometimes indention should be changed for a particular using.
* Worst of all, sometimes same code is used in different places where 
different indention levels are expected.
* Using spaces guarantee that code will look same in every editor but it 
is the simplest and not the most convenient way, the code should look 
_good for every editor user_, not _same_, so it tears down our community.
* It's less comfortable to use spaces for indention in every editor I 
use (at least because spaces allows caret position in the middle of 
indention and pressing <one of delete one char keys> deletes one space 
instead of the indention level, so it's easy to accidentally broke 
indention and use, e.g. 7 instead of 8 spaces).

And this isn't only a theory. In practice:
* I've never liked 8-chars indention, so I feels myself bad in d-p-l.org 
sources. Probably I'm not the only one.
* I accidentally brake spaces indention sometimes. Probably I'm not the 
less-trained-in-printing one.
* Some time ago a ebook version of d-p-l.org has been created. Walter 
had to change every 4-spaces indention in examples to 2-spaces indention 
for convenience reading on small PPC screen.
* Now everyone see 2-spaces indented examples in d-p-l.org instead of 
his, probably, preferred 4-spaces indented.

Am I mistaken? If no, am I missing some major spaces advantages? If no, 
lets use tabs. Perhaps, there is no tool that will convert (convert 
right, not somehow, see article) tabs<->spaces in D code.
