linelog is a heck of a lot faster than perl. If you want to do
this in production, I'd definitely do some speed benchmarks first.

Personally I'd either just write it out with linelog and then,
like Alan said before, post-process if you really can't stand
',"",' in the files, or write a new xlat in rlm_expr to quote a
non-null string and use that for all the attributes.

Some variant on linelog specifically for generating CSV/TSV files
might be worthwhile, but pretty much everyone's got along with
linelog just fine so far, so it doesn't seem to be worth the time
to write one.
