the preceding atom. It does work the other way around:
Example matches ~
\1\@<=,\([a-z]\+\) ",abc" in "abc,abc"
In the old regexp engine the part of the pattern after "\@<=" and
"\@<!" are checked for a match first, thus things like "\1" don't work

Example matches ~
\([a-z]\+\)\zs,\1 ",abc" in "abc,abc"
\@123<=
Like "\@<=" but only look back 123 bytes. This avoids trying lots
