Actually, you should not store into an argument. I'd argue it is a bug 
that the compiler does not complain. It's unnecessary, too:

	{Date. Time} inject: {} into: [:coll :each | coll, {each. each class}]

That's about as short as you can get now. More efficient is this:

	Array streamContents: [:stream |
		{Date. Time} do: [:each | stream nextPut: each; nextPut: each class]]

This version does not unnecessarily create lots of intermediate 
collections.
