Pathnames are short strings. No need to optimize for performance, instead optimize for clarity.
There have been times in darcs where the performance of path names was an issue.
Let me guess: Lots of (++) used in a left associative way compounded by lots of init, last and (reverse . dropWhile p . reverse)? If so, that's easily avoided by giving pathnames a structure. Lists have too little structure and operations are cheap at the wrong end. -Udo -- AMAZING BUT TRUE ...
