Java and Rust have gone the same route. collect is a terminal operation
creating a data structure given a potentially infinite, lazily
evaluated, stream. Rust uses iter for creating a stream from a data
structure, Java uses stream or parallelstream. Java's parallelstream
seems to be missing from Rust, but there is Rayon to provide a version.
D's std.parallelism does something of this, but it needs more work to
provide the tree-structured as well as scatter–gather internal
parallelism models.
