Is there any language that allows spaces in variable names

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

I know the language of Whitespace , but I'm interested in a language that was actually used for something other than a demo.

I ask this out of sheer curiosity.

In a way, yes. A few variable variable names are actually just keys to a higher level object. Both Coldfusion and Javascript come to mind. In Javascript you can write foo=bar , but you really said:

 window['foo'] = bar;

You can write just as easily

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

Different areas in Coldfusion can also be viewed as either (dict | hash | associative array) or name.

Of course, once you create a name with a space, it is harder for it to access without using the hash search syntax.

TSQL will allow you to use spaces in table and column names, since you have this between the square brackets [ ]

Theres a fantastic article that sql will let you get away from here http://www.sqlservercentral.com/blogs/philfactor/archive/2009/08/14/evil-code.aspx
