There is a lot of things in life we shouldn't do, but we do.  :-)
At least give us the choice, maybe via a compiler directive and keep
the compiler warning in place.  That way we can use it responsibly
when required, as in the case of implementing a true singleton. I'm
sure there are more examples. As it stands currently (my sample
singleton code) the developer can still screw up by creating a new
instance instead of going through the global function.
