I've been doing some Java lately, and it seems to me like Java libraries are often doing (and making the programmer do) a lot of work just to get back the dynamism that Python has by default. Many kinds of errors are only detectable at runtime: * dependency injection errors, * template errors, * magic annotation malfunctions, etc. The last one in particular actually seems less safe than Python's decorator mechanism. Java splits it in two parts, so that the annotation classes used at compile time are separate from the library that will process them to actually do something. If the latter part is somehow broken, the code will just do nothing, so you don't even get a runtime error. In Python, decorators are just functions that serve as annotations as well as doing the actual work. There is usually no separate processing part that can go missing. I've never encountered similar problems in Python.
