This is probably really a Meditation. OK by me if it is moved there.

I saw this neat blog post on Planet Perl. I got to think about an idea.

• Regular Expressions can be seen as unification.
• Code is executed with (?{ }), depending on how far the unification has gone.
• Backtracking in Regular Expressions could be used as Prolog backtracking.

Sounds like a good basis for implementing Prolog! Is there a simple way to compile unification/backtracking in a Prolog program to a Regular Expression?

I should write some code before asking, but I can't be the first (or the fiftieth) person to think of this. You could call other RE:s from the inserted code (the inserted code needs a functionality to fail).

I did search perlmonks and didn't find anything.
