class Object
# Returns true if this object is included in the argument.
#
# When argument is a +Range+, +#cover?+ is used to properly handle inclusion
# check within open ranges. Otherwise, argument must be any object which responds
# to +#include?+. Usage:
#
# characters = ["Konata", "Kagami", "Tsukasa"]
# "Konata".in?(characters) # => true
#
# For non +Range+ arguments, this will throw an +ArgumentError+ if the argument
# doesn't respond to +#include?+.

# Returns the receiver if it's included in the argument otherwise returns +nil+.
# Argument must be any object which responds to +#include?+. Usage:
#
# params[:bucket_type].presence_in %w( project calendar )
#
# This will throw an +ArgumentError+ if the argument doesn't respond to +#include?+.
