Nevertheless, one should eschew its use in public; in particular, in
error messages that a normal respectable user might see.  Normal users
can be consternated by an assertion that an illegal operation has been
attempted or performed.  The English language contains many words ... (

and "license" is not one of them) ... which can be used instead.

It can also work unreliably.  Consider

        D = new Date() ; D.setMonth(5)

which has about a 1 in 52 chance of doing what probably was not
expected; and consider the careless implementation of Zeller's
Congruence which was in a (draft?) RFC or similar in the nineteen-
nineties; and consider the implementation of Number.toString(B) in which
the final character was incremented if the remainder was a half or
more.
