Re: trouble with pattern, character collections

Thanks for explaining it to me.

So we've hit the true question:

Should '.' behave the same way as [^\n] ?

Who is going to write [^\n] if you can use '.' ?

From my point of view there is no use of [^\n] other than causing
surprise.

New arguments for keeping surprising [^\n] behaviour?

Let's ask in a different way: Is there a use case for [^\n] like
patterns at all (except that '.' which can be expressed as '.')?
