I dont see much value in distinguishing between eager and lazy,
particularly as this leads to an unusual display format.  What
difference does it make how the object was constructed?

Also, this is not avoiding "#<procedure" as suggested?  A simple
"#<promise OBJECT-ADDRESS>" is succinct and sufficient.
