Description
With this definition
Base.pairs(x::Cons) = (first(p) => last(p) for p in enumerate(x))
findall, findfirst, etc. will work with linked lists.
Or maybe even, since there seems to be no default method for pairs,
Base.pairs(x) = (first(p) => last(p) for p in enumerate(x))
(Of course, the latter would go in Julia, not a package)

Research direction
Start by inspecting the Cons implementation and the existing pairs and enumerate methods in DataStructures.jl, then check how findall and findfirst consume pairs. Confirm whether the change belongs in the package or Julia itself; done means linked-list Cons values support the intended lookup functions without breaking existing pair behavior.
