Depends.  If you think of it in terms of the default value being
shadowed by @var if it exists, returning to the default value after
a remove_instance_variable would seem reasonable.

This indirectly brings to mind another question, though -- when and
how often is the block supposed to be called, if given?  Once? 
Per-class?  Per-object?  Per-get?
