Thanks Philip.
One major problem we face is that eventually we want to allow multi-line
regex
search.
I was thinking, perhaps something along these lines is possible:
1. add a function that compiles the reverse of a given regex,
2. possibly have a mode that would reverse the input before matching,
But thinking about it more, it gets really complicated around handling
Unicode
properly.
May be you can use callouts with pattern like .*P(?C1)
In callout 1 you can doing needed things with last occurrence of searched
string and return 1 to find previous occurence.
