Static vs dynamic typing is always one of those topics that attracts passionately held positions. In the static typing camp we have the benefits of catching bugs earlier in the development cycle, eliminating altogether some classes of bugs in deployed systems, improved things like code-assist and other tool support, and enabling compiler optimisations. In the dynamic typing camp we have cleaner looking code, and greater flexibility and code malleability.
