Return of "exist" method

[mosuke5]

Hi! I have a question about "exist" method. Why is this function's return exception not ture/false?

For example, in branching processing juding from whether key exists or not, we must use exception.

cache = Memcached.new("localhost:11211")
begin
    cache.exist("my_key")
    key_exist = true
rescue Memcached::NotFound => e
    key_exist = false
end

if key_exist?
    ...
else
    ...
end

But, I think we should write following way.

cache = Memcached.new("localhost:11211")
if cache.exist("my_key")?
   ...
else
   ...
end
