It's a side issue.  It doesn't have the intended effect if you take it
out of context like that.  But it was not a general statement, anyway.
I was speaking specifically of something Stephen wrote:

Taken literally, the standard says "nothing but Dictionary".  But my
point is, if a Dictionary is a Collection of Associations, any such
Collection can be used.  This isn't a violation of standard.  It's
interpretation.  That's what "abstract" in "<abstractDictionary>" means.
 "If it walks like a duck and quacks like a duck, ..."

The only thing that stands in the way of that is #do:.  Dictionary>>#do:
isn't in the standard, so compliance is not really a problem.
