No spaces around single letter operators (and ()[], as well). Waste of monitor space. It's colour there. While it helps on minor expressions it will only scatter longer ones. I prefer line breaks on this. (This is the wish for better indentation (._.); )
Only assignment statement "=" is with spaces to distinguish to the equal to operator.

I allways hated

= Someexpression
? someBool;
= Some_other_bool

so this would be

= Someexpression
? someBool;
=Some_other_bool
