My module here:
Uses several perl keywords on the lefthand side of the fat-comma => operator.
The syntax highlighter has recognised "while" as a bareword here and not applied the keyword highlighting to it, but has failed to recognised "until" or "foreach".
Actually, I've just noticed it only displays like that in Chrome.
It works as expected in Firefox and IE.
