Re^4: What it mathches`

I'm missing your point. Nothing here contradicts what I said, and I don't see how anything here relates to what I said.

so felt free to use whichever perl I had handy.

That's fine (although it gives an error in 5.8.8). That's why I said "by the way". The goal was to discourage anyone from thinking it was acceptable to use it. It's buggy when used in conjunction with qr// and perhaps other features.

I think we're talking across each other. You said, "No assumption was made." I pointed out where the perl documentation shows that ^ assumes, without the /m flag, that there is only one line as an optimisation, which runs contrary to there being "]n]o assumption ]...] made". You said "$* doesn't exist anymore." I had originally described $* as deprecated twice, and said not to use it twice, so I wasn't sure why it needed further pointing out other than perhaps to say that it doesn't exist in 5.10 at all, so I merely pointed out why it worked for me: I'm using perl 5.8.8.

I pointed out where the perl documentation shows that ^ assumes, without the /m flag, that there is only one line as an optimisation, which runs contrary to there being "]n]o assumption ]...] made". I have no idea what that optimisation is, but how the regex engine optimises is well outside the topic of this thread. Any assumption it made affects performance, not result, so I don't know why you think I made an assumption.	[reply]
