Tabs vs Spaces (yes, again!)

PIG DISGUSTING

{
    int a    = 3;
    int ab    = 4;
    // ...
}


{
   int a  = 3;
   int ab = 4;
}

BEAUTIFUL AND NICE

{
    int a  = 3;
    int ab = 4;
}

Style 1 (all tabs) will look fucked up vertical alignment with different tab widths. Style 2 (all spaces) will look weird to those used to different tab widths. Style 3 (tabs to indent, spaces to align), on the other hand, is made of epic win because it allows one to change the tab width without losing the nice vertical alignment, and those who really like all spaces can easily have their editor auto-convert tabs to spaces.

Style 3 > Style 2 > Style 1. If you use Style 1, you're an asshole.

It's too bad Emacs doesn't already have some kind of format suitable for the storage and manipulation of hierarchical structures, and it is additionally too bad that this format that doesn't exist can't be compiled and stored in a binary file.
