Subject: [ruby-core:110554] [Ruby master Bug#19094] `sleep(nil)` vs `sleep()` and replicating the default implementation.

Issue #19094 has been reported by ioquatix (Samuel Williams).

Bug #19094: `sleep(nil)` vs `sleep()` and replicating the default implementation.

> sleep(nil)
(irb):1:in `sleep': can't convert NilClass into time interval (TypeError)
```

However, I feel that this makes implementing a compatible sleep method a little difficult.

```ruby
def sleep(time = nil)
  if time
    sleep_some(time)
  else
    sleep_forever
  end
end
```

Can we consider allowing `sleep(nil)` and `sleep(false)` to be the same as `sleep()` to simplify this behaviour?
