class HFunctor sig => Effect sig

The class of effect types, which must:

1. Be functorial in their last two arguments, and
2. Support threading effects in higher-order positions through using the carrier’s suspended state.

All first-order effects (those without existential occurrences of m) admit a default definition of handle provided a Generic1 instance is available for the effect.
