hash key to var name of value hash key value

[Une bévue]

i'd like to now if their is a simpler way to do that :

IN_NEWS=@h['IN_NEWS']

because here i do have to know their is a key of name "IN_NEWS"

want i want is to affet the value of all the @h['key_name'] to the
variable key_name ???

(as far as i remember well it's possible in php then i think this is
also possible in ruby ))))

Thinking out loud...

hash.each_key{|k|
eval("#{k}=hash[#{k}]")
}

There may be a better way, though...

hash.each_key{|k|
eval("#{k}=hash[#{k}]")
}

hash.each_pair {|k,v|
Object.const_set(k, v)
}
