Thank you, thank you.

In a sense I think they are the same. The main problem with using the CL
bitvector syntax is that binaries are usually much bigger, sometimes
mega-bytes.

I don't like the labels name and I am free to do as I want. :-) At least
until we are more people working on LFE, if that ever occurs.

That would work, but I don't really know how worried I am about the problem.
It was more a comment on that neither Scheme's hygiene and gensym are really
safe unless you use them as intended. We'll see what the users need.
