Wonderful -- error checking is not a general problem. Lets just make up
results for strange situations. Trying index outside the bounds of the
array? No problem, just return some random bits. Trying to pop an empty
stack? No problem, we'll just guess you probably wanted 0 (or maybe, on
Tuesday's, for variety, we'll return the null pointer or the empty list
In fact, lets get rid of all errors in programs. Up with the DWIM
instruction! Down with reliability!
