would your use of %-length operator interfere with
Lua's default meaning of % as a modulus operator. 

I am guessing there, because I don't think it will stay '%'.

My logic was that '-' is likewise used as unary prefix, and binary infix, so
my /hope/ was that the mechanism should be the same for any
character. It looked quite liberal in the source, seems to work but I am
not sure. It looked like unaries are protected by a high precedence and
that might cause unexpected results, haven't mulled that really.

As an alternative I
would suggest '$' character for your length op. On my US-en keyboard $
is next right to #.

Sure, $ may be better. It's really just exchanging one char in the source
but as I said, maybe it is cleaner to go for a built in function.

Maybe we find a character that has some association with 'length'
already. I think $ does actually, does'nt it?
