How to get some node's name?

[killa1218]

For example if we define field('var_name', $.identifier); in gramma.js. How can I get the name 'var_name' from an identifier node object? There is a property is_named to indicate whether current node has name, but no something like name or get_field_name().

If willing to use a cursor, may be the following sort of thing could work?
