Short Circuiting Fold

This pretty much explains it: http://crypto.stanford.edu/~blynn/haskell/foldl.html here I just review the article.

The rule of thumb is this:

• if you want short circuiting on foldr, use a lazy on the right combiner
• if you want short circuiting on foldl, use a lazy on the left combiner

/**
 * Fancy ID generator that creates 20-character string identifiers with the following properties:
 *
 * 1. They're based on timestamp so that they sort *after* any existing ids.
 * 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs.
 * 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly).
 * 4. They're monotonically increasing.  Even if you generate more than one in the same timestamp, the
 *    latter ones will sort after the former ones.  We do this by using the previous random bits
 *    but "incrementing" them by 1 (only in the case of a timestamp collision).
