```
> 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?
Otherwise, it's hard to proxy (e.g. fiber scheduler, or even just a plain old variable argument).
e.g.
```ruby
class Sleeper
def initialize(time = nil)
@time = time
end
def sleep
Kernel::sleep(@time) # Hard to get the behaviour of `sleep()` here without explicitly handling/checking.
end
end
```
