Well, the goal is to avoid blobs as much as possible, in favor of 
breaking out data into separate, meaningful fields whenever it makes 
sense.  That said, stream-encoded data (particularly compressed formats) 
does often need to be treated as an opaque blob.  However, in the 
context of the original discussion the current design has a "uint8" 
type, so the function of blobs is filled by using an array of unsigned 
bytes.  Only if we don't have unsigned integers is a "blob" type needed.  
Although in that case you *still* need to figure out an appropriate 
mapping of your blob type into the target language.

Um.  How is a "point" different from a normal x,y,z vector?
