Comment (by guest):
quote: {{{foo < 2.0.0}}} is weird. It says {{{foo-2.0}}} is ok, but
{{{foo-2.0.0}}} is not.
It is only weird because Data.Version has weird semantics for equality.
Most people expect 2.0 to be the same version as 2.0.0 and 2.0.0.0. If we
were to adopt the proposal to fix Data.Version so that these were truly
equal, then the weirdness would disappear.
(But I agree that a dependency like {{{foo <= 2.0}}} is definitely still
weird.)
