Re^2: @- Bug on the loose, lets isolate it

I think the point is not what the @- array contains, but that it contains anything at all. The supplied regex doesn't do any capturing, so the @- array should be empty. What we're seeing is that perl is creating a very large array for no reason. Doing so takes time, thus slowing down programs where it shouldn't. That's a Bad Thing.

Both `@-` and `@+` should contain at least one element each to show where the start and end of the match is. You're supposed to be able to derive $& from `substr( ..., $-[0], $+[0] - $-[0] )`.	[reply] [d/l] [select]
