> h3. String
> Anything between double-quotes.  Node-side this is just converted to bytes, so it could
really be used to represent *any* type so long as it is appropriately encoded.
> Examples:
> {code:style=SQL}
> SELECT "name" FROM cf;
> UPDATE cf SET "name" = "value" WHERE KEY = "key";
> {code}
> h3. UTF-8
> A double-quoted string literal that is prefixed with a "u" to indicated that it should
be encoded to bytes using the utf-8 charset node-side.
> Examples:
> {code:style=SQL}
> SELECT u"name" FROM cf;
> UPDATE cf SET u"name" = u"value" WHERE KEY = "key";
> {code}
> h3. Integer
> An undecorated numeric literal, converted to a 4-byte int node-side.
> Examples:
> {code:style=SQL}
> SELECT 10..100 FROM cf WHERE KEY = "key";
> UPDATE cf SET 1000 = "thousand", 100 = "hundred" WHERE KEY = "key";
> {code}
> h3. Long
> A numeric literal suffixed with an "L", converted to an 8-byte long node-side.
> Examples:
> {code:style=SQL}
> SELECT 10L..100L FROM cf WHERE KEY = "key";
> UPDATE cf SET 1000L = "thousand", 100L = "hundred" WHERE KEY = "key";
> {code}
> h3. UUID
> A string-formatted UUID supplied as an "argument" to a ctor/function formated string
({{uuid(<uuid string>)}}).  Node-side this is converted back to the corresponding UUID.
> Examples:
> {code:style=SQL}
> SELECT uuid(5f989e95-ae07-4425-b84a-6876ba106c66) FROM cf WHERE KEY = "key";
> UPDATE cf SET uuid(5621b93d-d3a2-4d22-8a59-bdb93202b6cb)  = "username" WHERE KEY = "key";
> {code}
> h3. TimeUUID (UUID Type 1)
> A string-formatted time-based UUID (type 1) supplied as an "argument" to a ctor/function
formated string ({{timeuuid(<uuid string>)}}).  Node-side this is converted back to
the corresponding UUID.  In addition to a string-formatted UUID, it should also be possible
to supply dates in a variety of formats which will result in a new UUID being created node-side.
> Examples:
> {code:style=SQL}
> SELECT timeuuid(2011-01-01)..timeuuid(2010-01-21) FROM cf WHERE KEY = "key";
> UPDATE cf SET timeuuid(now) = 1000L  WHERE KEY = "key";
> {code}
