Bar and Baz are keywords in the language and should therefore be highlighted. Foo is an arbitrary identifier and needs no special highlighting treatment.

If I separate the above tokens with whitespace, everything is fine. But if I do not separate them with whitespace (as in the above example), I only get appropriate highlighting for Baz, not for Bar.

Any suggestions?
