I can understand where you're coming from since I like static typing as well, but I don't think what you're saying is fair. It's good to be able to statically identify certain classes of errors so that you can, as you say, find and fix them within the IDE rather than having to resort to runtime debugging. What he (?) is saying is that, up until the point where you encounter the error at runtime, the fact that you can statically detect it shouldn't prevent you from running your code. This philosophy is obviously a tradeoff. It's good for prototyping since you don't have to make sure your whole program passes static analysis in order to test a particular code path. On the other hand, if developers get away with leaving such code in a large project (as a work in progress that never gets addressed, for example), this can create a maintenance nightmare. The solution to this is to not let people contribute code to the project which doesn't pass static analysis.
