Ok, maybe not everything, but alot of things are. I've recently come across a several situations that reminded me how great lists are, particularly in a loosely typed language like ColdFusion. There are tons of things that can be treated like a list in ColdFusion. Here's a short list of some of my favorites:

• Sentences are lists of words delimited by spaces.
• Lines of a page are lists delimited by a Carriage Return/Line Feed (CRLF).
• Paragraphs are lists delimited by a pair of CRLFs.
• File paths are lists delimited by forward or backward slashes. Use listLast() to grab the filename or listFirst() to grab the drive letter (windows).
• File names are lists delimited by a period. Use listLast() to get the file's extension.
• Decimal numbers are lists delimited by a period. Use listFirst() or listLast() to separate out the whole number or fraction.

All in all there are 20 functions in ColdFusion that handle lists - beyond those 20 are more that create obvious lists such as structKeyList(), arrayToList() and getClientVariablesList() - and even more that create less obvious lists such as decimalFormat() (decimals are a list), getDirectoryFromPath() (paths are lists), dateFormat() or timeFormat() (often lists delimited by slashes or colons). Still not convinced that lists are all that and a bag of chips? Jeff Peters actually wrote an entire book exclusively on ColdFusion Lists, Arrays, & Structures. Ahh structs, how I love ColdFusion structs, but that's a whole other post all-together...
