Yes, I do the same in leex for two reasons:

- You can distribute the generated scan module to users without leex.
- It is easier to print Erlang code than to build it, at least I think so.

Here the problem was to not use files, and generating LFE is easier than
printing it. I have an option to print the generated module if necessary.
