I don’t think it does.

It seems to me that const_iterator is analogous to pointer-to-const and const member functions. These are used in WebKit and the issues are different than for const local variables. It’s about whether the pointed-to thing can be changed, not whether a local variable can change. When the thing in question is not local, const is far more valuable.

Sounds easy to fix.
