Methods should support vararg predicates

[dgroup]

public boolean any(Predicate<T> first, Predicate<T> ... other);
public boolean all(Predicate<T> first, Predicate<T> ... other);
public Enumerable<T> select(Predicate<T> first, Predicate<T> ... other);

[dykov]

Should these methods return boolean or Enumerable<T> ?

[dgroup]

Boolean.

@dgroup, please check if we need vararg support for other methods?
