- I was using ranges for parsing initially but realized all my 
ranges were instantiated with ubyte at one point.
- you propose the fread interface (return numbner of read 
elements), I've tried that in the image library and it's not as 
nice as just returning a default value, such as zero on failure, 
and fail out of band.
