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