Patches welcome ;) But I agree.

The reason you have to pass in a string is because that is used as the
template for spacing etc. I agree that passing in the original text a
second time is annoying - that's why I wanted to change the API to take
the input string from a tree node.

As for the lens: is it really that cumbersome that you have to specify
the lens you want to use ? To me, it makes it a little clearer what is
happening.
