Ahh, thanks.  The spaces.  And turning on REUSEADDR made playing 
with the code a fair bit more fun.

But, I mainly made the note to motivate a D aficionado to update 
and fix the Rosetta entry so that it at least compiles. Perhaps 
the whole *be bold* thing, and make the sources as idiomatic and 
correctly concise as D deserves.  As a for instance, task 
description calls for Goodbye as the text in the solution.
