I'm struggling to write a test for this. I thought this would work:

	| griffle |
	self createClass: #Griffle.
	griffle := env at: #Griffle.
	self should: [griffle compile: 'nowTime ^ TimStamp new'] raise:

but it doesn't. First it fails because there's no UndeclaredVariable,
but the second time it runs, even though env at: #TimStamp is
KeyNotFound, inspecting the env and evaluating "TimStamp" yields nil.
That's fine if you're in a WorkSpace, which will automatically create
bindings for you, but not so much here.

Or am I misreading my test failure? Could an inspector autocreate the
binding? Even though the env's undeclared is empty, the root
environment's contains #TimStamp->nil.
