No, mutating of datasets is no longer supported.  You can kind of fake it 
in ruby <2.4, but on ruby 2.4+ they really are frozen.  If you just want to 
apply a module to a dataset, you can do:

  ds = ds.with_extend(MyModule)

This will not work if your API takes a dataset/relation and does not return 
a value.  You'll need to change your API to return the dataset/relation to 
use in that case.
