They share most of the problems of global variables. While not
evil, it's better to avoid module-level mutables. This makes
the code more testable, simpler to understand, less bug prone,
and makes functions more usable for other purposes. In D there
the attribute "pure" is present also to enforce such better
coding style.
Let's not forget that since global variables are 'per thread'
that the issues involving them lessen and are less evil than
before.
