I noticed a very popular post up on Stack Overflow yesterday, it was tagged as _code golf_. The idea is you complete the task or problem (golf) in the least number of characters (strokes).
However, after dabbling in Ruby and Python these last few weeks, I really see a lack of functions in native CFML that address dealing with common data structures such as structures and arrays.
Also, the lack of chaining of functions in CFML makes for verbose code, which I have mentioned before.
I know some would create pure Java objects to deal with these issues, but it would be nice to see some of the Ruby-esque features implemented in native CFML.
