The implementation is a bit different but the no-no on mutating the
blah.fixture_class_names is the same

yes :-)

A simpler example in which merge! and merge= wouldn't be the same
would be

class Foo
def self.bar
@bar.dup #prevent people mutating me!
end

def self.bar=(value)
@bar = value
end
end

Clearly Foo.bar.merge!(...) will not accomplish much here
