I'll ask a meta question. What is your assurance that a particular hash value won't have to do double duty as both a value and a nested hashref? In other words, are you sure you're never gonna have: 
A--B
A--B--X
A--B--Y

[download]
because that would require B to be both a terminal and a non-terminal.
