Now I understand what you meant with "123 does not match where abc matches"! I misunderstood the whole look ahead concept. I find very useful this explanation: http://stackoverflow.com/questions/2973436/regex-lookahead-lookbehind-and-atomic-groups > > Incidentally, I cannot recall ever having a use for \@=. As the help says, it > does the same thing as \&. I think lookaheads are good for defining more conditions which would be difficult to define in one expression. Like "four-letter world containing a vowel". Without lookaheads I think this could be done only with regex defined with four branches (each fixing a vowel on certain position).
