How can I write `($typeof(x[])).split(":")[0]` better?

[treeform]

I just want to know the name of the ref type:
    
    
    echo x                             #error: expression: `$`(x)
    echo x[]                           #(....)
    echo typeof(x)                     #ref Bar:ObjectType
    echo typeof(x[])                   #Bar:ObjectType
    echo ($typeof(x[])).split(":")[0]  #Bar
    
    
    Run

I guess I am looking for some thing like typeof(x[]).plainName ?
