I agree with both evaluations, and have just posted a proposal to
replace parallel for-loops with a new data constructor.
(I still like list comprehensions. But they need to be cleaner.)

Question with boldness even the existence of a God; because, if there
be one, he must more approve the homage of reason, than that of
blindfolded fear.... Do not be frightened from this inquiry from any
fear of its consequences. If it ends in the belief that there is no
God, you will find incitements to virtue in the comfort and
pleasantness you feel in its exercise...
