This is intended. Bash doesn't allow a local copy of a variable to override a readonly global one. This can be a potential security hole,
--- You can look at it that way, but it also hinders modular programming. If I declare a variable to be local, I wouldn't expect it to fail and be overridden by some global namespace pollution. It is overridable, but not easily. Might be nice to have some way to declare a var local to a function that can be protected from random namespace pollution.
