Poolable¶

Overview¶

Object pooling mixin, for cases where creating new objects is expensive, and we'd rather mark some objects as able to be reused (i.e. 'in the pool'). This provides a pool of objects for each type it is invoked on. It allows for getting "new" objects that can either be constructed OR pulled in from a pool, and requires that the objects are essentially able to "re-run" the constructor. Then when putting the object back in the pool, references should be released, so memory isn't leaked.
