At our job we use a homebrew C++-like language. Now some people are planning to rewrite a core part of the problem to be completely dynamic, only using key-value to control the behavior of a large number of things. There is no namespaces and the value is an Object (base class for all classes), so you always have to cast. The absolute horror it will be to debug this mess when people starts to use it, my god.
