If it doesn't complain, it's happy with the syntax. Parentheses are
allowed.

Neither would be much more efficient, as they are both just doing the
same thing, and the lsearch has to read from a file as well. If the
number of tests gets quite large, then maybe a DBM lookup would do
better, but I think you'd need quite a lot of entries for that to be
worth it.
