Thinking in RegEx – when is a mind shift required?

David has written a great post on thinking in RegEx.  I have seen this many times with different languages or platforms where a shift in thinking is required to really use the language/platform effectively. 

Ones that spring to mind:

• SQL (set based thinking)
• NAnt (tag based thinking)
• Bash (process/task based thinking)

Read David’s post and please comment on any other language/platform that made you shift your mind.
