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

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

I ask this out of pure curiosity.

In a way, yes. Several languages's variable names are really just keys to a higher-level object. Both Coldfusion and Javascript come to mind. In Javascript, you can write foo=bar, but what you've really said is:

window['foo'] = bar;

You could just as easily write

window['i haz a name'] = bar;

The various scopes in Coldfusion can also be treated as either a (dict|hash|associative array) or a name.

Of course, once you've created a name with whitespace, it's harder to access without using the hash lookup syntax.

TSQL will allow you to use whitespace in table and column names aslong as you have it between square braces [ ]
