         * Filters the types of paths to include in the result.
         * The result will contain only the paths of types for which the predicate returned {@code true}.
         * It is recommended to apply a filter for retaining only the types of paths of interest,
         * because it can resolve ambiguities when a path could be of many types.

A partial type argument list cannot be empty; at least the first argument must be present.
The list is a prefix of the full list of type arguments, leaving the remaining arguments
to be inferred. Loosely speaking, type arguments may be omitted from "right to left".
