regex look behind

I noticed that Ruby supports lookaheads (??=), but does ruby support look
behinds?

I can't get the syntax (?<=) to work. Is the syntax possibly different?

Thanks

Zach

No, it doesn't. Anyway, you can compile your Ruby 1.6.8 or 1.8 with the
new regex engine oniguruma that already supports it:
