Given that the default entries behind the non-existent keys don't actually exist, something like "virtualdict" might be appropriate.

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?
