Every once in a while everyone of us encounters a programmer that disregards existing reusable code and creates his/her own "standard library" for everything, from trimming string to creating random number to cleaning the kitchen sink. We all might have been one too, at one time or another. I'm not saying that this bundle is a case of the above, but it's giving me a similar feeling. :-)
A commendable effort, David. But there really are a lot of wheels being reinvented here.
