Look-behind proposal in trouble

[Erik Corry]

I'm not convinced that the current proposal is easier to implement than the
real thing.  Take a look at the patch, it's trivial.

The lack of variable length lookbehind is a big annoyance in most
languages.  Search for the term and you'll find lots of frustrated perl
users.

On the other hand I don't think adding variable length lookbehind to the
spec makes it any easier to optimize /.+$/.
