I understand that, and actually having thought about it, it seems that I
was just confused by the documentation.  I would suggest:

    "Answer a new instance of Dictionary initialized from the keys and
    values of Associations in anArray.  This method is for convenience
    only;  it allows its argument to be conveniently specified as a
    braced Array literal that is structured accordingly:  {'key' ->
    'value'. 'another key' -> 'another value'}."

And maybe suggest that any other usage is considered "misuse" and is
"strongly discouraged or bad things will happen"...  :)  Basically I
think it should make it very clear that it's there for convenience.
That would also explain why Array>>#from: answers its argument instead
of a new instance, which seems inconsistent with Collection and Dictionary.
