   I think this should be more explicit, e.g.:
   ```
   // The length-prepended version is used for:
   // - in v1 data pages: definition levels, repetition levels, and RLE-encoded 
boolean data
   // - in v2 data pages: RLE-encoded boolean data
   length-prepended-rle-bit-packed-hybrid: <length> <encoded-data>
   // The non-length-prepended version is used for:
   // - in v1 data pages: dictionary indices
   // - in v2 data pages: definition levels, repetition levels, and dictionary 
indices
   rle-bit-packed-hybrid: <encoded-data>
   
   length := length of the <encoded-data> in bytes stored as 4 bytes little 
endian (unsigned int32)
   encoded-data := <run>*
   ```
