Making Rascal structures looking better

Question

To keep structures clear is it possible to name them. So essentially I asking for a 'struct' in Rascal. So eg:

list[tupple[map[str,int],int]]

to:

treeLabel :: str
occurences :: int
treeData :: map[treeLabel,int]
treeNode :: tupple[treeData,int]
tree :: list[treeNode]
tree x=[];

How about using Abstract Data Types?

See Rascal Tutor. The above could then look like this:

data MyStruct = ms(str treeLabel, 
                   int occurrence, 
                   map[treeLabel, int] treeData,
                   tuple[TreeData td, int n] treeNode,
                   list[TreeNode] tree);

given some variable m with a myStruct value you can access elements with the usual dot notation:

m.treeLabel;
m.treeLabel = "xyz";

etc.
