 responds both to array and (some) stringy operations.  Note that,
 like a C<Buf>, its size is measured in whatever the base unit is,
 which is not always bytes.  If you have a C<my Blob[bit] $blob>,
-then C<$blob.elems> returns the number of bits in it.
+then C<$blob.elems> returns the number of bits in it.  As with buffers,
+various native types are automatically derived from native unsigned int types:
 
+    blob1       Blob[bit], a bit string
+    blob2       Blob[uint2], a DNA sequence?
+    blob4       Blob[uint4], a hex string

 These types do (at least) the following roles:
