Comment (by darij):
I fear I don't understand the species code well enough to complete the
review. :( How on earth does the {{{compose}}} method know to do
plethystic rather than usual composition? I assume the answer lies in
{{{_compose_term}}} in generating.series.py, but that's some unreadable
code with unreadable doc.
You are right about {{{_name}}}; what I wrote was bull. Sorry!
Please remove the trailing whitespace in your code (such as in {{{return
res }}}).
