* For now only the last argument gets integer encoded, so make sure that: 1) every multi bulk commands implemented will have the last arg that is indeed a value, and not used otherwise. 2) to explicitly call the function to encode the object in MSET and other commands where there are multiple "values".
* Man pages for MSET MSETNX and SRANDMEMBER, Z-commands, ...
-* ZSETs missing stuff: ZINCRBY
* Use strcoll() to compare objects in sorted sets, like it already happens for SORT.
* LPOPPUSH, EXPIRE, EXPIREAT, ZSCORE, SRANDMEMBER tests.
* Write docs for the "STORE" operaiton of SORT, and GET "#" option.
* Append only mode: testing and a command to rebuild the log from scratch.
-* Profiling and optimizations. For instance the commands lookup is probably starting to eat too CPU being a simple list. To implement binary search or an hash table lookup can be a win probably.
* Redis-cli should be able to select a different DB than 0 using some switch.
