ability to set an item that never expires about ccache HOT 2 CLOSED

fetch doesn't do anything fancy (e.g., there's no singleflight mechanism), so it isn't too burdensome to re-implement it in your app to behave how you want.

Essentially, fetch is currently:

	item := c.Get(key)
	if item != nil && !item.Expired() {
		return item, nil
	}
	value, err := fetch()
	if err != nil {
		return nil, err
	}
	return c.set(key, value, duration, false), nil

You could simply remove the item.Expired() check:

	item := c.Get(key)
	if item != nil {
		return item, nil
	}
	value, err := fetch()
	if err != nil {
		return nil, err
	}
	return c.set(key, value, duration, false), nil

As-is, items are only evicted when the cache is full. Alternative, I'd recommend just using a very large ttl:

const MAX_TTL = time.Duration(1<<63 - 1)

Fair enough. As I mentioned in my comment on the other issue, I'd recommend updating the doc comment on Fetch to clarify that it's not doing anything you can't do exactly as well with Get and Set (I wasn't 100% sure at first because it's calling the private set rather than the exported Set—that's also the case above, so your example code wouldn't actually compile if implemented outside the package—but when I followed through to the implementation of set I could see that there's nothing special there).
