I'd like to believe you're coming in at the wrong level.  Many
languages have built-in syntax to access ``members of objects'' or
``fields of records'' that can often be applied to accessing
``properties of nodes''.  In this case, the grove API is the
language's native syntax.

Where native syntax is not applicable, groves most closely resemble
container classes (dictionaries, mappings, hash tables; lists, arrays,
sequences).  Again, a language's standard container class interface or
protocol can be used.
