Hi,

I have been looking for a package that implements resource pooling? I.e. a package that implements a pool of (reference counted) resources to avoid dynamic allocation of “expensive” resources such as large arrays, images, network connections etc.

Best regards,  
Jesper

There is a `CachingPool` for use with `pmap`, for example. Is that sort of what you are after?

Not quite, I need something that implements the [Object pool pattern](https://en.wikipedia.org/wiki/Object_pool_pattern) like [GitHub - steinwurf/recycle: Simple resource pool for recycling resources in C++](https://github.com/steinwurf/recycle)
