In the spirit of making the target expression look like a template for the generated elements,
{school: [student...] for school, student in student_school_list}
hmm -- this seems a bit non-general -- would this only work for a list? maybe you would want a set, or???
so could be get a defaultdict comprehension with something like:
{ school: (default_factory=list, student) for school, student in student_school_list }
But I can't think of an reasonable syntax to make that work.
