# Wrapping an array in an +ArrayInquirer+ gives a friendlier way to check
# its string-like contents:

# variants = ActiveSupport::ArrayInquirer.new([:phone, :tablet])
#
# variants.phone? # => true
# variants.tablet? # => true
# variants.desktop? # => false
class ArrayInquirer < Array
# Passes each element of +candidates+ collection to ArrayInquirer collection.
# The method returns true if any element from the ArrayInquirer collection
# is equal to the stringified or symbolized form of any element in the +candidates+ collection.
#
# If +candidates+ collection is not given, method returns true.
#
# variants = ActiveSupport::ArrayInquirer.new([:phone, :tablet])

# variants.any?(:phone, :tablet) # => true
# variants.any?('phone', 'desktop') # => true
