The trouble is, I can think of several occasions in which I assumed an
object could only have one instance---and then later found reason to
wish I had written it so that there could be two.
No, this doesn't happen in all cases. But it seems to me it happens
often enough that one should carefully examine any assumption that
there can be only one instance. Or be prepared to go back and make
some major changes later.
