Is there any language that allows spaces in its variable names
Is there (or was there ever) any non-trivial language that allows spaces in its variable names?

I am aware of the language [Whitespace][1], but I'm interested in a language that was actually used for something besides demonstration.

I ask this out of pure curiosity.
