Getting a syntax error in here on "node", looking for }.

The definition is from another imported manifest, and looks like:

define shareSslPublicKeyWithNode( $node, $key) {

----------

  shareSslPublicKeyWithNode{

    "Share CA public key to ${myNode}" :
      node => $myNode
    , key => "ca"
    ;

    "Share admin public key to ${myNode}" :
      node => $myNode
    , key => "admin"
    ;

    "Share ${myNode} public key to ${myNode}" :
      node => $myNode
    , key => $myNode
    ;

  }

------------

Reduced, same error:

shareSslPublicKeyWithNode{ "Share CA public key to ${node}" : node => $node , key => "ca" }

Syntax error at 'node'; expected '}'
