Expose accessors so they can be composed

Is your feature request related to a problem? Please describe. I would like to access the internal accessors, so that I can create new ones, while using the built-in accessors internally.

Describe the solution you’d like Exposing the accessors, like env.accessors.

Describe alternatives you’ve considered At the moment, I’m importing lib/accessors/xxx, which is far from ideal, as they are not part of the public API.

Additional context

Example:

        asIntRange: (value, range) => {
            value = asInt(value);

            if (value < range[0] || value >= range[1]) {
                throw new Error(`to be within range [${range[0]},${range[1]}]`);
            }

            return value;
        },

where asInt is the lib/accessors/int.js.
