I'm confused - do you mean that some rows in the result set from the 
database have columns "missing", rather than just set to NULL? That's 
not something I've ever come across before.

By the way, you still haven't addressed my point about this whole setup 
only giving you 3 states, and there being no particular reason you won't 
need a 4th later.

Why? That's what isset() is for, which is where this whole discussion 
started; I'm not sure why you've suddenly mentioned is_null().


> Deprecate expand() so it's use is not possible may be another 'fix'?

Surely there are plenty of ways to use extract() without attempting to 
give meaning to missing variables.
