The implementation of fluid-let is trivial, provided you don't have
more than one thread to deal with.  That's why they were withdrawn,
bad behavior when multiple threads are involved.  Parameters have
their own problems, especially when mutated rather than rebound,
but they're an advance on fluid-let.

Micropayment advocates mistakenly believe that efficient allocation of
resources is the purpose of markets.  Efficiency is a byproduct of market
systems, not their goal.  The reasons markets work are not because users
have embraced efficiency but because markets are the best place to allow
users to maximize their preferences, and very often their preferences are
not for conservation of cheap resources.  --Clay Shirky
