in thread Tied Hashes vs. Objects

Dear fellow monk, thanks for your advice. Rest assured, the actual implementation of these "special" hashes (case-insensitive keys, read-only hashes, substring keys, whatever they come up with) is of little concern here, and can -- and has actually mostly been -- dealed with. The issue about performance came up, because, well, these operations may be called A LOT. So if there is any significant difference betweeen tied hashes (which map hash operators to OO-style methods, basically) and calling these methods directly, I would really like to know.
