I would like a stream editor that was easy to use. sed is powerful and it can work on huge files without loading them all into memory but the model it uses is very hard to understand IMO. It's such that you'll try almost anything before getting out the manual to work out how to achieve the smart effects that it can achieve. Then you hit the sort of "WTF" one where your problem with SED has no google-able answer. So rock-on the potentially less powerful stream editor that I can end up using more than once in a blue moon (ok barring sed 's///' which is easy enough to remember and commonly useful).
