Subject: Hash as Checklist

Hello,
I need to check if a word is in a list. I'm using hash because the
lists can be long (i'm under the impression hash is faster than array).
Basically I'm only interested that a key exists. I have to create
entries like:

h = {
"one" => true,
"two" => true,
"three" => true,
"four" => true,
"five" => true
}

So h["one"] gives true, and h["seven"] returns nil. But typing the
dummy value "true" is a waste of effort, and there's an ugliness in
there. Is there a better way to design a simple checklist?

Thank you for your help
