Or PL/I that Sean mentioned. I seem to remember a variable was assumed
to be a double if its name started with 'n' and other types for other
initials. So when you made a typo, nubmer_of_things was was not
reported as an error but rather contained garbage, and possibly of a
different type than what you expected. But of course it all worked
through autoconversions, until you suddenly got an underflow on what
you thought was an integer.
