I think it's interesting the mentality of dynamic typing die-hards. I find it much easier (for complex projects) to just type "const" where appropriate and let the compiler think about mutability for me, than to think about mutability myself. The mental overhead is definitely superlinear with the complexity of the project, and typing "const" a few times lets me use that resource for more subtle correctness issues. Of course, one problem with C++ (and, to a lesser extent, C) is that many of those subtle correctness issues are direct results of the type system in the first place. Go figure.
