Calls the block, if given, with each element of `self`; returns a new
Array containing those elements of `self` for which the block returns a
truthy value:
    a = [:foo, 'bar', 2, :bam]
    a1 = a.select {|element| element.to_s.start_with?('b') }
    a1 # => ["bar", :bam]

Returns a new Enumerator if no block given:
    a = [:foo, 'bar', 2, :bam]
    a.select # => #<Enumerator: [:foo, "bar", 2, :bam]:select>

Array#filter is an alias for Array#select.
