Using Hash in define

[Jean Baptiste Favre]

Hello,
I want to pass a hash as parameters for a define

$hash = { name => 'aname', key1 => 'akey', key2 => 'anotherkey' }
mydefine { 'define': hash => $hash }

define mydefine ( $hash ) {
notice("Hash is as follow: name is ${hash[name]}, key1 is
${hash[key1]}, key2 is ${hash[key2]}")
}

When running it , always got an error message:
Error 400 on SERVER: hash is not an hash or array when accessing it with
name.

What I'm doing wrong ?

Regards,
JB

Answer to myself: always double check for misspelling variable names...
