  Back when i was working on bitmanip with the bitfield mixin, i 
had to re-write it with newlines and tabs, and then have it 
expand it as text and output it and see what the actual output 
was before i could debug it.

  The output was... informative.

  That said, rolling your own mixins should really be the last 
resort. You're dumping a lot into a single line of code you can't 
trace, follow, debug, or look at.
