# A module gets a name when it is first assigned to a constant. Either
# via the +module+ or +class+ keyword or by an explicit assignment:
#
# m = Module.new # creates an anonymous module
# M = m # => m gets a name here as a side-effect
# m.name # => "M"

# Uses blank? because the name of an anonymous class is an empty
