Andrei suggested auto ref to fix this problem, and Walter
implemented it, but he misunderstood what Andrei had meant,
I missed this detail of the story :-)
Walter has suggested that we just redefine ref itself to do
what I just
described rather than using auto ref or
Thanks for the insights! I suppose we'll get a chance to see
where things stand at this year's dconf.
It's quite interesting that D's concept of r-values seems less
developed than C++. Here's hoping that that only results in a
better thought out solution.

Auto ref parameters seem to be just what I need. Thanks! I'd
still be curious if anyone has additional information regarding
the rationale at play (I'm spoiled, reading TDPL and having each
