Collect only requires that the collection is iterable, for which providing an eltype() function is optional. I don't know if it is possible to check at runtime if eltype() exists for the collection then it could use that instead of Any, otherwise it would have to iterate the collection to find all the types and either accumulate the results in an Any collection as it goes and copy them to the right type collection later, or iterate twice.
