I'm the accidental maintainer/guardian/dungeon keeper of a bunch of scary code at work, which happily does:

    if (false != aBooleanVariable)

I still can't parse that without stopping and thinking (and sometimes cursing the original author). To me, with booleans, this can only sanely be written:

    if (aBooleanVariable)

Code with literals is often worse than functionally equivalent code without; literals are complexity. And I hate literal comparisons with true and false for booleans. Aargh.
