There is a function that parses paths: fnamemodify, expression that gets last
part of a path: fnamemodify(path, ':t'). But there is probably a better
solution
either using match groups or defining a new function with split+join:
let
&l:includeexpr='substitute(substitute(v:fname,"::","/","g"),"[^/]\\+$","&/&.pm","g")'
