Re: Hash or bidimensional Array when key is case insensitive?

Hi, I've to take a decission about using an bidimensional Array or a
Hash to store parameters. Of course I prefer Hash since the order
doesn't matter and I know the param name I'll need.
The problem is that the param name is case insensitive.

Example:

tag = qweqweqwe
Method = INVITE
NAT=yes

is the same as:

Tag = qweqweqwe
METHOD = INVITE
Nat=yes

If I use an bidimensional Array and need to get "method" param I willl
need to do:

method = params_array.find { |param| param[0] =~ /^method$/i }[1]

And if I use a Hash I'll do the same:

method = params_hash.find { |param| param[0] =~ /^method$/i }[1]

Is there any advantage using Array or Hash in my case (key is case insensitive)?

Another approach is to store it in a hash, but downcase the key before
storing and retreiving:

irb(main):001:0> h = {"get" => "value_for_get", "post" => "value_for_post"}
=> {"get"=>"value_for_get", "post"=>"value_for_post"}
irb(main):002:0> method = "gEt"
=> "gEt"
irb(main):003:0> h[method.downcase]
=> "value_for_get"

Jesus.
