# Add #blank? method to NilClass class.
class NilClass
# Nil is always blank
#
# @example
# nil.blank? # => true
#
# @return [TrueClass]
#
# @api public
def blank?
true
end
# Calling `try` on `nil` always returns `nil`. It becomes especially helpful
# when navigating through associations that may return `nil`.
#
def try(*args)
nil
end
def try!(*args)
nil
end
# Since NilClass is immutable it cannot be duplicated.
# For this reason #try_dup returns +self+.
#
# nil.dup! #=> nil
