My personal view is that constructors (even explicit ones) and functions
give differing impressions to the user. In this case, I would worry that
having an explicit constructor would encourage people to use it without
being aware of the subtle and complex issues which this thread has exposed.
Having to use a function (and even more so, having to choose which of two
functions with differing semantics to use) makes people stop and think a
little.
