Since there was a comment about Perl5 style vs .NET style when I first posted my proposal to es-discuss, too, I just wanted to explain about the background of my proposal. I proposed Perl5 compatible lookbehinds because I thought it was relatively simple to implement. Moreover, I am not confident that I can write a lookbehind proposal based on .NET implementation, in the manner used in the ECMAScript specification. As Jason Orendorff wrote before, the lookbehind supported by .NET is a strict superset of what I have proposed. So, if you or someone else submits another lookbehind proposal based on .NET and it supersedes my proposal in a later version of ECMAScript, from the point of view of users, that would look like just an enhancement. My hope is that lookbehind assertions are certainly supported in RegExp of ECMAScript in the near future.
