Deja vue.  I believe this discussion went around 4 or 6 years ago on
BIX.  Unfotunately I don't remember the reason for rejecting it.
Seems like some logistics of handling a constructor on something that
may already be partially constructed.  Basically who calls the default
constructors if neither invoked constructor or the called constructor
constructs it.  The compiler either has to realize this and only
construct it once or it will get constructed twice.

The bottom line was it was hashed around quite a bit, as it looks nice
on the outside, but presents some real problems in implementation.
