No, that would suggest to me something like
a wrapper object that delegates most of the
mapping protocol to something else. That's
even less like what we're discussing.
In our case the default values are only
virtual until you use them, upon which they
become real. Sort of like a wave function
collapse... hmmm... I suppose 'heisendict'
wouldn't fly, would it?
