Would anyone be averse to changing pytree.Node's __repr__ so it  
includes the name of the name of the symbol the node represents?

The only downside is that it makes the __reprs__ longer... But I  
think its worth the length:

Node(313:simple_stmt, [Node(298:import_name, [Leaf(1, 'import'), Node 
(279:dotted_as_name, [Node(281:dotted_name, [Leaf(1, 'foo'), Leaf(23,  
'.'), Leaf(1, 'bar')]), Leaf(1, 'as'), Leaf(1, 'bang')])]), Leaf(4,  
'\n')])
OR just names:
Node(import_name, [Leaf(1, 'import'), Node(dotted_as_name, [Node 
(dotted_name, [Leaf(1, 'foo'), Leaf(23, '.'), Leaf(1, 'bar')]), Leaf 
(1, 'as'), Leaf(1, 'bang')])])
OR the original:
Node(313, [Node(298, [Leaf(1, 'import'), Node(279, [Node(281, [Leaf 
(1, 'foo'), Leaf(23, '.'), Leaf(1, 'bar')]), Leaf(1, 'as'), Leaf(1,  
'bang')])]), Leaf(4, '\n')])
