Honestly, I think we already have way too many of these kind of helpers. 
IMHO they don't really help, they hurt readability. You should know how 
the list works anyway, and if you do, then it's a no-brainer what's 
first and last. If you don't, then you are bound to screw up in other ways.

Just my 2 cents.
