Do you think we are missing an alternative of monad-var or a related project?
The aim of this library is to provide a unified set of operations (
swap, various strict
mutate* functions and their derivatives (like mutate-and-return-the-old-value) and a certain interface for
MVar-like things) over all common variable types:
When possible type classes are generalized to be over abstract containers rather than variables: e.g. it'd make sense to implement
MonadRead TChan and
MonadMutate_ Vector instances, but no such instances are provided right now.
There are also some lenses to be described in an upcoming blog post.
