I think it's fine when the language has sufficiently strict types for string concatenation. Unfortunately, many languages allow `string + int`, which is quite problematic. Java is to blame for some of this. And C++ is even worse since literals are `const char[]` which decays to pointer. Languages okay by my standard but not yours include: Python, Ruby.
