It should be noted that one can use Obj'Image exclusively once it is 
available, because the prefix can always be qualified if necessary and that 
adds exactly one character to the attribute reference (and it's a lot 
shorter if qualification isn't needed).

My plan (once I'm using a Janus/Ada that supports it consistently, probably 
a few years still even though it is supported in the leading edge version 
now) is to completely forget the subtype version exists and use the object 
version consistently.

(Note that J-P was one of the few people that didn't support this extension, 
so it's fair for him to be consistent - but he was wrong then and he's wrong 
now. ;-)
