Henning,
thank you very much for your effort. It is a very useful path, indeed.
Just one question, would your use of %-length operator interfere with
Lua's default meaning of % as a modulus operator. As an alternative I
would suggest '$' character for your length op. On my US-en keyboard $
is next right to #.

It would be great if you could provide your implementation as a
standalone patch.

Mit freundlichen Gruessen,
