Dear all,
may I suggest to include this quotation of Patrick Burns in the fortunes
package? :-)
Best,
Roland

A good reason to use '&&' rather than '&' is if evaluating
whatever is on the right will create an error if what is on
the left is FALSE. '&&' and '||' stop if they already know
the answer from seeing the left side. So they are likely faster
by a few nanoseconds, but it's the ability to stop before you
go off a cliff that is probably the key feature.
