What do you mean by adding second substitute?
set includeexpr=substitute(...)\|substitute(...)
? This won't work: assume that it runs `let includefile={put inputexpr here}'.
Would you really write this with bar? You can use nested substitutes, but it is
not required here:
let &l:includeexpr='substitute(v:fname, "::", "/", "g").".pm"'
Another warnings:
1. Using `:set' for local options. I know that this is what was written in
example, but you should use `:setlocal'.
2. You do not require to escape colon, escape in example escapes dot that means
`any character except newline' in unescaped state.
3. Using `let &l:optname=...' instead of `setlocal optname=' is more readable.
