I've asked this before, without getting a clear answer: What constitutes
a "true constructor"?  I understand the problem with dispatching to
things whose parts haven't been initialized yet.  But what I'm looking
for is a definition of what a "true constructor" is.

Which programming languages have true constructors?
C++ constructors have some (different) problems.
